The 1st Northamptonshire Rifle Volunteers were a unit of the British Army raised from 1859 onwards as a group of originally separate Rifle Volunteer Corps (RVCs). They later became the 4th Volunteer Battalion of the Northamptonshire Regiment and saw action in the Gallipoli and Palestine campaigns during the First World War. Converted into a searchlight unit between the wars, they served in the defence of the United Kingdom and as an infantry regiment in liberated Norway during the Second World War. Postwar they continued in the air defence role until 1961 when they reverted to infantry as part of the Royal Anglian Regiment.
