Littleport is a small town in the Fens of Cambridgeshire, England, north of Ely and north west of Welney. It lies on the Bedford Level South section of the River Great Ouse, close to Burnt Fen and Mare Fen.

Littleport is the site of the Littleport Riots of 1816. War-weary veterans from the Battle of Waterloo had returned home, only to find that they could not get any work, and that the grain prices had gone up. They took to the streets and smashed shops and other buildings until troops came to put an end to the riots.
