The 1934 Detroit Lions season was the fifth in franchise history and the first in Detroit, as the team moved from Portsmouth, Ohio, to Detroit after the 1934 season. Under head coach Potsy Clark, the Lions won their first ten games (of which the first seven were shutouts) then lost three straight in an eight-day span to end the season at 10–3. They finished in second place in the NFL Western Division, three games behind the undefeated Chicago Bears. They ranked first in the NFL in scoring defense and second in scoring offense.

Dutch Clark was a consensus All-NFL pick at quarterback and led the league with 1,146 yards of total offense and ranked second in scoring, third in rushing yardage, and fourth in passing yardage. End Harry Ebding led the NFL with 264 receiving yards. The Lions also boasted four of the NFL's leading rushers: Clark (third with 805 yards); Ernie Caddel (sixth with 528 yards); Ace Gutowsky (seventh with 517 yards); and Glenn Presnell (12th with 413 yards). The team's total of 426 rushing yards against Pittsburgh on November 4 remains an NFL single-game record.

The Lions played the NFL's first Thansksgiving day game on November 29, 1934, starting the team's longstanding tradition of hosting Thanksgiving games. The team played its home games at University of Detroit Stadium.

Standings

Move from Portsmouth and preseason

Prior to 1934, the franchise had played as the Portsmouth Spartans in Portsmouth, Ohio, a city with a 1930 population of 42,560.

In March 1934, a group from Detroit, led by WJR radio owner George A. Richards, purchased the Portsmouth franchise and the rights to all players on its roster, including stars Dutch Clark, Glenn Presnell, George Christensen, and Ox Emerson. Detroit sportsman Irvin (Cy) Huston was appointed as the general manager, owing to "his inttimate knowledge of the game." Huston announced that the University of Detroit Stadium had been secured as the site for the team's home games. He added that negotiations were underway to sign additional players, including the University of Michigan's All-American center Chuck Bernard. Bernard ultimately signed with the club in September.

On April 10, 1934, NFL president Joseph Carr formally presented an NFL franchise to the Detroit investor group at a luncheon at the Detroit Statler Hotel. Huston accepted the franchise from Carr.

Later in April, Huston announced that he had agreed with the New York Giants for the Detroit club's opening game to be played in Detroit on September 23. The game would be a homecoming for the Giants' star quarterback and Detroit native Harry Newman.

On June 9, Huston announced that the team would conduct its early season training at Cranbrook School for the first three weeks of September. Huston noted that Cranbrook had several first class gridirons and a dormitory where the team's training table would be established.

On July 22, Huston announced that the Detroit club would be known as the Lions and would wear blue jerseys with silver for the jersey numbers, helmets, and pants. Asked what shade of blue would be used, Huston replied: "I don't know. They've had me looking at so many blues I'm blue in the face. But anyway, it's the kind of blue, I am told, that will match with silver."
