Sport in Luxembourg

There are many athletics clubs in Luxembourg representing most of the country's main towns. The largest club is CAL Spora Luxembourg, with a membership of 400 members. At an organisational level, the same clubs are often affiliated to both the Luxembourg Athletics Federation (FLA) and the Luxembourg Triathlon Federation, the governing bodies for athletics and triathlon, respectively.

Luxembourg's sole Olympic gold medalist was an athlete. Josy Barthel won the men's 1500 metres at the 1952 Summer Olympics in Helsinki. Another Luxembourgish athlete, Michel Théato, won the marathon at the 1900 Summer Olympics in Paris, but, as his nationality was only proven to be Luxembourgish after his death, his medal is credited to France, where he lived, instead.

One of the world's foremost cross-country running competitions takes place in Diekirch, the IAAF permit meeting Eurocross.

Cycling is the sport in which Luxembourg has had most success at a professional level, and is one of the main participatory sports amongst the general population. The country's flat terrain lends itself to the sport, with the Tour de Luxembourg being run around the country on an annual basis as a prelude to the Tour de France.

Famous Luxembourgish cyclists of the past include Nicolas Frantz, Charly Gaul, François Faber, Andy Schleck and Benoît Joachim of whom the first four won the Tour de France (Frantz having done so twice). Altogether, Luxembourgish cyclists have won the Tour de France five times, ranking Luxembourg fifth overall. Currently, there are three Luxembourgish cyclists on the UCI ProTour, who are Bob Jungels, Ben Gastauer, and Jempy Drucker.

Among female cyclists, Elsy Jacobs is notable as the first ever women's road racing world champion in 1958, and as a holder of the women's world hour record.

Tennis is a popular sport, as it is across western Europe. There are 53 tennis clubs in the country, the oldest of which (TC Diekirch) was founded in 1902. The governing body is the Luxembourg Tennis Federation. The Fortis Championships Luxembourg are held in Luxembourg each year, and are ranked as a Tier III tournament on the WTA Tour.

Luxembourgers have had little success in professional tennis. Gilles Müller, considered the best men's player the country has ever produced,[2] reached the quarter-finals of the 2008 U.S. Open and also of the 2017 Wimbledon Championships. He has a career high ranking of 21st. Women's players that have reached the top fifty include Anne Kremer (18th) and Claudine Schaul (41st). The Luxembourg Davis Cup team competes in Group II. The Luxembourg Fed Cup team competes in Group I.

Cricket is a minority sport in Luxembourg, played predominantly within the British expatriate community located in and around Luxembourg City; very few native Luxembourgers play the sport. The game's governing body is the Luxembourg Cricket Federation, whose primary purpose is to promote the game to the non-British population.

The dominant club is the Optimists Cricket Club, which plays in the Belgian league, which it has won on three occasions. The Optimists serve as an auxiliary governing body to the LCF, organising the small domestic Luxembourgish league. The club fields multiple subsidiary teams in the domestic league, but the focus is on the Belgian league.

The sport's domestic received a boost from the patronage of Pierre Werner, former Prime Minister of Luxembourg, who served as President of the OCC and after whom the main cricket ground in Luxembourg is named the Pierre Werner Cricket Ground in Walferdange.

Football is the most popular sport in Luxembourg. The top-flight National Division is the premier domestic sports league in the country. Luxembourg was amongst the first countries in the world to be introduced to football, with the National Division being established in 1913, and the national team playing its first match in 1911.

The game is more popular in the south of the country, having developed earliest in the industrial Red Lands and Luxembourg City. Only once has the National Division been won by a team not from the south of the country. Historically, Jeunesse Esch has been the most successful domestic club, having won the National Division on 28 occasions (out of a total of 104). Since 2000, the league has been dominated by F91 Dudelange, which has won the league on fifteen occasions. Dudelange also became the first Luxembourgish team to compete in the Group Stage of the Europa League during the 2018–19 season.

The national team, nicknamed d'Léiwen ('The Lions'), was one of the weakest in the world, having not ranked above 150th in the world since 2002. They have since reached a record high of 82 in September 2018. The team achieved moderate success in the 1964 European Championship, when the side beat the Netherlands and almost progressed to the semi-finals. The most famous Luxembourgish footballer is Jeff Strasser, who has made a successful career in the French and German leagues. Luxembourg's most famous past players include Louis Pilot and Guy Hellers, both of whom also coached the national team after ending their playing careers.

Rugby union is a minor but growing sport in Luxembourg, with participation numbers having drastically increased over the past decade, now residing at 2,370 licences. Club Rugby in Luxembourg is successful at both junior and senior level. Rugby Club Luxembourg's first 15 plays in Bundesliga 1, with Walferdange Rugby and RCL II competing in lower German leagues. Walferdange also sports the nation's only female 15s side, which plays in the second Belgium division, competing for promotion. CSCE and Rugby Club Terre Rouge only have youth-sides which compete in Belgium and France. A fifth club, the Rugby Eagles Luxembourg, was founded in 2019 and became an official Member of the Luxembourg Rugby Federation in June 2020. This club is exclusively a child-centered rugby project.

The Senior Men National 15s is one of the highest ranked national teams among all team sports in Luxembourg, currently sitting at 64th place, making it one of Luxembourg's most successful national teams. Having gained promotion to a higher league in the European Championships for the 2018-2019 season, the ambition is to further rise in the ranking. This success has been fuelled by the junior national sides, which compete in the European National Championships at U18 and U20 level, in both Rugby 15s and 7s.

Hockey is a minor but growing sport in Luxembourg following the arrival of an Englishman who plays hockey.
