The 2005 English cricket season was the 106th in which the County Championship had been an official competition. Before it began, a resurgent England cricket team had won four Test series in a row, going unbeaten through the 2004 calendar year. The start of the international season saw England defeat Bangladesh 2–0 in their two-match series, winning both Tests by an innings. This was followed by a tri-nations one-day tournament that also featured Australia. Australia still started the Test series as favourites but most fans expected England to put up a challenge.

Despite losing the first Test by 239 runs. England came back to win the second and fourth Tests, and draw the third and fifth, to win the Ashes for the first time since 1986–87. It was the 72nd test series between the two teams with England finally winning 2-1. Andrew Flintoff dominated with both bat and ball for England, scoring 402 runs – more than any Australian – and taking 24 wickets – more than any Australian bar Shane Warne. Warne also had a spectacular series, with 40 wickets at a bowling average of 19.92, and 249 runs, but most of his efforts came in losing causes – such as making 42 with the bat in the second innings of the second Test.

In domestic cricket, Nottinghamshire won the County Championship, for the first time since 1987, and Durham enjoyed promotion in both the shorter and the longer form of the game. Surrey, the 2000 and 2002 Championship winners, were relegated in the Championship, and played in Division Two in both the Championship and the National League in 2006. Hampshire Hawks won the 50-over knock-out C&G Trophy, but were relegated in the National League, which Essex Eagles won in emphatic fashion, as they lost only one game and had a 14-point gap to the runners-up, Middlesex Crusaders.

The Australian women also toured England at the same time as the men, and England won the Women's Ashes 1–0 after two Tests. However, the Australian women won the ODI series 3–2. To round off the season, investors in partnership with Leicestershire arranged an International 20:20 Club Championship, which Pakistani team Faisalabad Wolves won.

Month by Month review April

The cricket season started early, on 8 April, with MCC playing the Champion County, or at least it would have done if the rain had not delayed the start till the next day. The other games played were all between the first-class counties and university teams. The first matches showed a bumper crop of centuries, with little joy for bowlers, but there were no surprises. The MCC ended up beating Warwickshire.

Away from the cricket field, on 8 April the ECB announced that triangular One Day International tournaments would no longer be played in England. On 11 April Kevin Pietersen, England's South African-born all-rounder was reported to have a foot injury that could see him miss the start of the season, and Chris Schofield began his case for unfair dismissal against Lancashire, which he eventually won.

The first round of the Frizzell County Championship saw Warwickshire gain maximum points, with Hampshire also winning in Division One. Durham replicated Warwickshire's feat in Division Two, where Worcestershire also won.

The first round of the totesport National Cricket League was held on 17 April, though most of the games were affected by the rain. 5 results were possible in the 8 matches. Rain continued to bedevil the second round of the County Championship, with only Yorkshire and Durham securing wins. In the MCC University matches, Bradford/Leeds UCCE shocked an injury-weakened Surrey by beating them at the Oval.

The second round of the totesport League saw a heavy defeat for Surrey away to Durham, with other wins for Northamptonshire, Middlesex, Kent and Sussex, which left Middlesex and Durham at the top of the tables at the end of April.

In the third round of the Championship, Surrey thrashed what already appear to be Division One whipping boys Glamorgan to go third, with Nottinghamshire and Warwickshire also recording big wins to go second and first respectively. In the second division, Essex and Lancashire beat Somerset and Worcestershire respectively. However, Durham, who sat this round out, led the table at the end of April, from Essex and Worcestershire, with Derbyshire and Leicestershire propping the table up.

May

May started with one-day games played on 1 and 2 May. Middlesex established themselves at the top of Division One after winning their first three matches. Yorkshire and Durham were the unbeaten teams in the Second Division. This was followed by the first round of the C&G Trophy, which for the last time included the minor counties and Scotland, Holland, Denmark and Ireland. However, there were no upsets. Durham lost to Derbyshire by 1 wicket, and Leicestershire beat Somerset by 3 wickets in the only all first-class county fixtures.

The fourth round of the Championship saw Gloucestershire sent Glamorgan down for another heavy defeat., as title contenders Hampshire and Nottinghamshire win against Middlesex and Surrey respectively. Surrey were found guilty of ball-tampering in this match, which later led to all their cricketers being fined by Surrey, and to the loss of 8 Championship points. The Second Division saw wins for Durham, Essex, Lancashire and Yorkshire. Whilst these games were being played Loughborough UCCE chalked up the second victory for a UCCE team this season by thrashing Worcestershire by 8 wickets in a game the students dominated in throughout.

On 10 May the Bangladeshis got their tour off with a three-day game against the British Universities, which was drawn. The fifth round of the Championship saw Surrey dish out another defeat to Glamorgan as Middlesex and Sussex won. The Second Division saw Durham maintaining their lead at the top with a 9 wicket win against Lancashire. Worcestershire overcame bottom club Derbyshire, with Yorkshire beating Leicestershire in the only other decided game.

Essex, Lancashire, Hampshire, Worcestershire and Durham all won their totesport games on 15 May, with Leicestershire beating Surrey to continue Surrey's dismal form. The quarter-finals of the C&G Trophy followed, as did a tour match between the Bangladeshi's and Sussex in which the tourists lost by an innings and 226 runs, boding ill for the impending Test series. On 20 May Surrey finally won a totesport League game, beating fellow wooden spoon candidates, Scotland, in Edinburgh by five wickets.

20 May saw the start of another Championship round. Glamorgan lost yet again, this time to Hampshire, and in the other first division tie, Kent beat Nottinghamshire by 196 runs. Division Two saw Worcestershire beat Essex, as first-placed Durham drew with second-placed Yorkshire, and Lancashire drew at Somerset. At the same time, Bangladesh put up a stronger performance in Northampton in a match severely hampered by rain. The last round of the County Championship in May saw Nottinghamshire beat Gloucestershire to finish may top of Division One. Warwickshire beat Hampshire by ten wickets to leave them third and second in the table respectively, as Kent and Surrey drew to keep them in fourth and fifth. The table remains propped up by Glamorgan, who are strong favourites for relegation, with Sussex, Middlesex and Gloucestershire in places six to eight. Durham did not play in this round of the Championship, but remained in first place in Division Two, with Yorkshire missing a chance of taking over as leaders when they drew with Essex. Also in the round Somerset beat Northamptonshire and eighth placed Leicestershire beat ninth- (and bottom-) placed Derbyshire.

The Test match season finally started on 26 May, with Bangladesh completely overwhelmed in just over two days. After being dismissed for 108, Bangladesh could only watch as England made 528 for 3 declared, Marcus Trescothick top-scoring with 194. In their second innings, the tourists could only muster 159 as they went down by a mammoth innings and 261 runs. The one-day league games played over the Spring Bank Holiday weekend left Middlesex top of Division One, with Essex one win behind them with two games in hand. Gloucestershire, Hampshire and Nottinghamshire (who had not won a game by the end of May) were in the relegation spots. As with the County Championship, Durham led the Second Division from Yorkshire, with Derbyshire, Scotland and Leicestershire occupying the bottom three places.

June The eighth round of the Championship saw Hampshire beat title rivals Nottinghamshire and Kent beat Gloucestershire, and then lose 8 points for the poor quality of the Maidstone pitch. The other First Division matches were draws, with Glamorgan avoiding defeat after following-on against Sussex. The Second Division saw four draws. Meanwhile, the students of Cambridge UCCE edged past Middlesex by 2 wickets. The Second Test against Bangladesh at Chester-le-Street was another one-sided affair. 5 wickets from Stephen Harmison, on his home ground, helped dismiss the Bangladeshis for 104. Trescothick's 151, Ian Bell's 162* and Graham Thorpe's 66* saw England to 447 for 3 declared. Although Bangladesh did better in their second innings, their 316 saw them lose by an innings and 27 runs.

After another totesport League round, the top division of the Championship continued with Kent thrashing Glamorgan, Warwickshire thrashing Gloucestershire and local rivals Surrey and Middlesex drawing. In the Second Division, Durham pulled away further at the top with another win, this time against Essex, with Worcestershire also scoring a win against Somerset. However, the main focus was on the warm-up games for the NatWest Series and the first ever Twenty20 International between England and Australia. The only surprise in the warm-ups was a welcome win for Bangladesh over Worcestershire, which provided a welcome confidence boost to the Bangladeshis before they took on England and Australia in the NatWest Series.
