Knattspyrnufélag Fjarðabyggðar (KFF) was an Icelandic football club from the town of Fjarðabyggð located on the east coast of Iceland.

History

The club was founded in 2001 with a merger of three local clubs, Íþróttafélagið Þróttur Neskaupstað, Ungmennafélagið Austri Eskifirði and Ungmennafélagið Valur Reyðarfirði. The next year, for the first time, Fjarðabyggð sent a women's team to play at league level. In 2010 Ungmennafélagið Súlan Stöðvarfirði came into the merger.

In 2022, the club merged with Leiknir Fáskrúðsfjörður to establish the new Knattspyrnufélag Austfjarða.
