Bodajk Futball Club Siófok, often known more simply as Siófok, was first established in 1921. Initially operating as Siófok SE, the club has undergone several name changes over the years and in 2005, merged with Bodajk Football Club to create its current incarnation. Over the years, Siófok have bounced between the various divisions in the Hungarian league system, enjoying several spells in the top tier along the way.
After gaining promotion to the top flight in 1985, the club went on to enjoy its longest spell in the division to date, remaining there until they suffered relegation again in 1994. They returned in 1996 and were relegated once more in 2000. Since the turn of the 21st century, the club have began to yo-yo fairly rapidly between the first and second tiers. The team achieved its most recent promotion to the first division ahead of the 2010-11 season.
To date, the club's only major honour has been a Magyar Kupa win. Their victory in the competition came in 1984, after they defeated Győr 2-1 in the final. This result also gained them qualification for their first major continental tournament, the European Cup Winners' Cup. The side's best performances in the top flight have been two 4th place finishes, which were achieved in the 1991-92 and 2003-04 campaigns.
A number of former Siófok players have also represeted the Hungarian national team. Some of the most notable examples include József Kanta, Ákos Koller and Zoltán Pollák.
The team play their home matches at the Géza Révész Street Stadium, known in Hungary as Révész Géza Utcai Stadion. The stadium takes its name from a street in the city, which was in turn named after a prominent psychologist, who was born in Siófok. The venue is able to hold a maximum of 10,500 supporters.
