 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.When the Scottish National Leagues were introduced in 1973, Killie were placed in the 3rd Division by the Scottish Rugby Union.
