The Somerset and Cornwall Light Infantry (SCLI) was a light infantry regiment of the British Army. It was formed in October 1959 by the merger of the Somerset Light Infantry and the Duke of Cornwall's Light Infantry, and was itself merged with three other regiments of the Light Infantry Brigade in 1968 to form The Light Infantry.

The Somerset Light Infantry (Prince Albert's) was a light infantry regiment of the British Army, which served under various titles from 1685 to 1959. In 1959, the regiment was amalgamated with the Duke of Cornwall's Light Infantry to form the Somerset and Cornwall Light Infantry which was again amalgamated, in 1968, with the King's Own Yorkshire Light Infantry, the King's Shropshire Light Infantry and the Durham Light Infantry to form The Light Infantry. In 2007, however, The Light Infantry was amalgamated further with the Devonshire and Dorset Regiment, the Royal Gloucestershire, Berkshire and Wiltshire Regiment and the Royal Green Jackets to form The Rifles.
