The Belgium national cricket team played its first international match in 1905 against the Netherlands. Their best performance in European competition was winning the ICC European T20 Championship Division 2 undefeated in 2011. In Twenty20 International (T20I) cricket, Belgium reached a peak world ranking of 37th in May 2023. The team's record includes a notable 2–1 series win over Austria in 2021.

Historically, the Royal Brussels Cricket Club and Antwerp Cricket Club have been among the most prominent and successful clubs, with the former's ground in Waterloo serving as a frequent venue for international matches.

In 2025, the federation partnered with Destino Legends Sports LLC to launch the EUT20 Belgium, a professional franchise league featuring six teams from cities including Antwerp, Bruges, Brussels, Ghent, Leuven, and Liege.

The inaugural EUT20 season, scheduled for May 2026, will attract global stars such as Wanindu Hasaranga, Angelo Mathews, and Rassie van der Dussen. Former England captain Eoin Morgan serves as the league's global brand ambassador. To ensure local development, the league mandates a (2 - 4 - 4 - 6) model, requiring at least two Belgian players in every starting XI.

Cycling

Cycling is a very popular sport in Belgium. It is governed by the Royal Belgian Cycling League, which is split between the Dutch-speaking WBV and the French-speaking FCWB. Many Belgian cyclists have been successful, and some of the greatest cycle races take place in Belgium, especially in road bicycle racing, though other bicycle racing disciplines such as mountain bike racing or track cycling also count a number of Belgian champions and races. The best Belgian cyclist of all time, Eddy Merckx, nicknamed the Cannibal, won the Tour de France and Giro d'Italia 5 times each, won the Vuelta a España once, the UCI Road World Championship 3 times, had many classic cycle race wins and set the hour record, among other achievements. Belgium has been one of the most successful countries in road cycling since the origins of the sport, with one of the oldest races being held in Belgium, Liège–Bastogne–Liège, which was first held in 1892.

At the Olympic Games, Belgium has won four gold medals for road cycling, with two victories for the Belgian men's team in the team time trial (at the 1948 and 1952 Summer Olympics) and two for André Noyelle and Greg Van Avermaet for the individual race. Belgium has had the most World Championship gold medals (25) with 3 victories by Rik Van Steenbergen and Eddy Merckx and 2 by Georges Ronsse, Briek Schotte, Rik Van Looy and Freddy Maertens. Belgian cyclists have also performed very well in the 3 grand tours. Ten cyclists have won the Tour de France 18 times between them, making of Belgium the country with the most Tour de France wins behind France. Besides Eddy Merckx, Philippe Thys won the most prestigious tour 3 times while Firmin Lambot and Sylvère Maes won it twice. The last Belgian winner at the Tour de France however was Lucien Van Impe in 1976. At the Giro d'Italia, Belgium has had 7 wins, being the second most successful country in terms of wins after Italy.
