Kilmarnock Rugby Football Club is a Scottish rugby union club which was founded in 1868, and is based in Kilmarnock, Ayrshire in west central Scotland. They play in West Division One. Often simply referred to as "Killie", their ground is at Bellsland in Kilmarnock, and they were formerly based at Rugby Park (hence its name). One of the oldest rugby clubs in Scotland, Kilmarnock Football Club owes its existence to KRFC as an internal dispute about which football rules to adopt resulted in a breakaway in early 1869 by those who preferred to play Association Football.
