The full name of the club is Koninklijke Fusieclub Merelbeke (Royal Mergerclub Merelbeke) and it has green and blue as club colours.

The club joined the Belgian FA in 1942 under the name Vlug en Vrij Merelbeke (Quick and Free Merelbeke), receiving matricule number 3551 and choosing yellow and green as club colours.

A first title came in 1954 when VV Merelbeke became champions in the Second Provincial Division, but the club relegated immediately the season after, where it would remain until 1973, when it dropped to the Third Provincial Division.

At that point the colours were changed to yellow and blue and the new club played at the stadium of VV Merelbeke.

After the merger, it took four more seasons until 1992 before the promotion to the Second Provincial Division was won, at which point the name was changed to the current KFC Merelbeke.
