Uniao Desportiva Vilafranquense is a Portuguese football club from Vila Franca de Xira, Lisbon District. It currently plays in the Liga Portugal 2, the second tier of the Portuguese football league system, following its promotion in 2019. The other only time when the club had played in the second tier was in 1987–88 season, when that level was still regionalised.
History
The club was created in April 12, 1957 with the merger between four local sports clubs: Grupo de Foot-Ball Operario Vilafranquense, Aguia Sport Club Vilafranquense, Hoquei Clube Vilafranquense and Ginasio Vilafranquense.
In the 2016–17 Taca de Portugal, Vilafranquense defeated G.S. Loures, Vilaverdense F.C. and G.D. Vitoria de Sernache to reach a fourth-round tie at home to F.C. Pacos de Ferreira of the Primeira Liga. They beat the top-flight team 1–0 on 20 November, with a goal by Marocas. In the next round (last 16), they lost by the same score at Vitoria S.C., also of the Primeira.
In the 2018–19 Campeonato de Portugal, Vilafranquense came second in Serie C behind U.D. Leiria. In the play-offs, they dispatched Lusitania F.C. and then Leiria on penalties to win promotion. This was the club's first time in a national second division. On 23 June in the final at the Estadio Nacional against Casa Pia A.C., the club drew 2–2 then lost 4–2 on penalties.
Due to the inadequate facilities of their Campo do Cevadeiro, Vilafranquense had to play their LigaPro home games 50 kilometres away at the Estadio Municipal in Rio Maior.
