Football in San Marino

Football is the most popular sport in San Marino, as well as in Italy, the country within which it is an enclave.

Domestic football
The San Marino Championship, founded under the auspices of the FSGC (San Marino Football Federation), is the premier footballing competition in San Marino. 16 teams take part in the competition. In 2007, UEFA granted San Marino a spot in the 1st Qualifying Round of the Champions League. In 2007 league champion S.S. Murata was the first team to represent San Marino in the Champions League when they participated in the 2007–08 competition, losing to Finland's Tampere United.

San Marino also have a representative in the Italian system with Victor San Marino (formerly San Marino Calcio) playing in Italian football's Eccellenza. San Marino Calcio played their home matches at the Stadio Olimpico of Serravalle. They were founded as early as 1960, though at times have gone under different names and not been associated with the Sammarinese FA. They have returned as Victor San Marino after a 2 year absence in 2021.

San Marino also have two cup competitions in the country: Coppa Titano, founded in 1937, in which all the teams in the league compete, and the Super Coppa Sammarinese which is between the winner of the cup and the winner of the league.

San Marino has no women's league, with them purely being represented in the Italian league system. This began as early as the 1980's, though the team only lasted 7 years and resulted in most of the players moving to play with Italian clubs. The FA attempted again in 2000, bringing together players for training and building up to entering the Italian league. As the project strengthened, they organised friendlies against Italian sides and in 2004-05 they would enter the Promozione, then called the Serie D, as San Marino Academy. For the first few years the team is predominantly Sammarinese and a national team is added to the long-term plans by the FA around 2013. Today, San Marino Academy continue to represent the nation in Italian women's football. They competed in the 2020–21 Serie A (women) for their first season in the top flight, but were relegated. The team are not listed as mainly Sammarinese anymore though, and no national side has formed as of 2022, the last in UEFA to do so. Problems of dual nationality have also struck, with Chiara Beccari being capped for the Italian U-19 team.

International football
The San Marino national team played its first unofficial international match in 1986, achieving a result of 0–1 against the Canadian Olympic team. San Marino's first competitive game was on 14 November 1990, scoring 0–4 against Switzerland in the European Championship qualifier. San Marino have participated in the qualifiers of every European Championship and World Cup, but have not won a match in either.

During this same competition, on 7 February 2007, San Marino were close to drawing with the Republic of Ireland, Stephen Ireland had scored in the 94th minute, within 8 seconds of the final whistle which resulted in them staining a 1-1. The goal scored by San Marino was their first in a European Championship qualifier since scoring 4–1 to Austria in 1998.

San Marino are as of November 2022 placed bottom in the FIFA World Rankings at 211th. On 10 September 2013, Alessandro Della Valle scored the first goal in competitive matches in five years, resulting in a 5–1 loss to Poland.
