MFK Karviná is a football club located in Karviná, Czech Republic, which plays in the Czech First League. The club took part in the Czech First League on two occasions in the 1990s, never surviving for more than one season. It played in the Czech 2. Liga between 2008 and 2016, when it was promoted to the First League. The team's colours are green and white.
Karviná as a multi-ethnic city of Cieszyn Silesia was a home to many football clubs, which were established by particular ethnic groups after World War I. At that time many football clubs of Polish, German, Czech and Jewish communities were founded. Most known and strongest Polish club was Polonia Karwina founded in 1919. After World War II German and Jewish clubs were not re-established. Czech and Polish clubs still existed until the 1950s, when as a part of communist unification of sport life in Czechoslovakia Czech clubs were joined to ZSJ OKD Mír Karviná and Polish Polonia Karwina incorporated into that club.
The club merged with Jäkl Karviná in 2003, taking the name MFK Karviná. The 2003–04 season saw the club play in the Regional Championship, finishing fourth but being promoted to the Czech Fourth Division due to higher-finishing teams declining the opportunity to promote. The club subsequently spent two seasons in the Czech Fourth Division, finishing fifth in their first season and third in the 2005–06 season, winning promotion to the MSFL. The club finished 8th in their first season back in the MSFL in 2006–07 and went on to finish fourth in the 2007–08 season. They then bought the license for the second division from league champions Sigma Olomouc B, and thus qualified to play in the Czech 2. Liga. Having played in the Second League since 2008, the club celebrated promotion to the First League after the 29th round of the 2015–16 Czech National Football League.
