Associazione Sportiva Roma, commonly referred to as Roma, is a professional football club based in Rome, Italy. Founded by a merger in 1927, Roma has participated in the top tier of Italian football for all of its existence, except for the 1951–52 season. Roma has won Serie A three times, in 1941–42, 1982–83 and 2000–01, as well as nine Coppa Italia titles and two Supercoppa Italiana titles. In European competitions, Roma won the Inter-Cities Fairs Cup in 1960–61 and the UEFA Europa Conference League in 2021–22, while they finished runners-up in the 1983–84 European Cup, the 1990–91 UEFA Cup and the 2022–23 UEFA Europa League.

The Serie A, officially known as Serie A TIM for sponsorship reasons, is a professional league competition for football clubs located at the top of the Italian football league system. The winners are awarded the Coppa Campioni d'Italia trophy and the scudetto, a decoration that they wear on the jersey the season after the victory. It has been operating as a round-robin tournament for over ninety years since the 1929–30 season. It had been organized by the Direttorio Divisioni Superiori until 1943, the Lega Calcio until 2010, and the Lega Serie A ever since. Serie A is regarded as one of the best football leagues in the world and it is often depicted as the most tactical and defensively sound national league. Serie A was the world's strongest national league in 2020 according to IFFHS, and is ranked second among European leagues according to UEFA's league coefficient – behind the Premier League, and ahead of La Liga, Bundesliga and Ligue 1 – which is based on the performance of Italian clubs in the Champions League and the Europa League during the previous five years. Serie A led the UEFA ranking from 1986 to 1988 and from 1990 to 1999.
