The Huntingdonshire Cyclist Battalion was a bicycle infantry battalion of the British Army. Formed in the Territorial Force in February 1914, it remained in the United Kingdom throughout the First World War. After the war, in 1920, it was converted to infantry and became the 5th (Huntingdonshire) Battalion, Northamptonshire Regiment in the Territorial Army. The battalion saw extensive service in the Second World War, fighting in France in 1940, Tunisia from 1942–43 and later Sicily and Italy from 1943–45 before ending the war in May 1945 in Austria. It continued to serve after the Second World War until May 1961 when it was amalgamated with the 4th Battalion, Northamptonshire Regiment to form the 4th/5th Battalion, Northamptonshire Regiment.
