Portimonense Sporting Clube is a Portuguese sports club founded on 14 August 1914 and based in Portimão, most notable for its professional football team, which currently plays in the Primeira Liga. It also fields various youth teams and a veterans team in football, as well as teams in basketball.
Situated in Algarve's second largest city, its stadium, the Estádio Municipal de Portimão, has a capacity of 9,544 spectators after undergoing renovation in early 2011. The club never won any major honours, but participated in the Primeira Liga for several seasons.
Portimonense's zenith was in the 1980s, a decade in which the club only played its football in the top division, also competing in the UEFA Cup in 1985–86. They reached the semifinals of the Taça de Portugal three times, in 1983, 1987, and 1988.
Estádio Municipal de Portimão is the current stadium of Portimonense S.C.. It is located in the centre of Portimão in the Algarve, Portugal and was opened in 1937 for local football club Portimonense S.C.. Its capacity is 9,544 people. It hosted Portimonense's stay in the Primeira Liga in the 1980s.
In 2006, Portimonense were forced to play away from the Estádio Municipal in the Estádio Algarve, which – built for Euro 2004 – is 70 kilometres from Portimão. In February 2007, however, Portimonense returned home and the Portimão Municipality purchased the site five months later. This allowed the renovations required for the hosting of higher level competition: the installation of green seats (in the colours of the city), new turnstiles and security facilities.
In the 2009–10 season, Portimonense won promotion to the Primeira Liga for the following season. The summer of 2010 was a time of further renovation of the stadium, as modifications were made to the pitch and drainage system, as well as the west stand, bringing the capacity to 9,544 at the cost of €800,000. The construction took longer than expected and the club had to wait until the turn of the year before they could use their stadium again. The club's first home league match in the renovated stadium was on 6 February 2011 against Paços de Ferreira, who emerged victorious with the only goal of the game.
