Kilcullen town sports predate the GAA. The club was founded in 1889, and at first wore green and gold. They changed to black and white to honour the New Zealand national rugby union team ("All Blacks"), who played in Dublin in 1905. Their nickname, "The Rags", comes from a friendly game against Isles of the Sea where the Dubliners insulted the Kilcullen team's shabby kit.
Kilcullen were beaten by Clane in the 1892 county final. Pat Garrett's Kilcullen team controversially beat Ballymore to win the 1915 junior championship and cause a major shock in their first senior championship match by defeating serial champions Roseberry, (the Kilcullen curate Fr Byrne had to intervene when the referee was assaulted), but lost to Maynooth in the county semi-final. The following year they contested their second county final winning the semi-final against Roseberry on objection. Kilcullen lost successive intermediate championships in 1954-1955. After becoming Intermediate champions in 1961, Kilcullen beat Monasterevin, Military College and Kill in a new took semi-final by 1-7 to 1-5, Eamonn Gilesman scored 1-1 for Kilcullen. They were forced to wait until the following year as a series of objections dogged the other semi-final, and lost to Moorefield 0-2 to 2-11.
In 2007 Kilcullen were relegated to Intermediate status, following a 0-12 to 1-12 defeat by Naas.
