Bodajk FC Siófok, or generally short BFC Siófok is a Hungarian football club based in Siófok, a small town on the shores of Lake Balaton. The club was founded in 1921 as Siófok SE (SE = abbr. f. Sport Club). The component Bodajk in the club's name stems from a merger (probably rather take-over by) with Bodajk FC in 2005. The colours of the club are yellow and blue.
