The East Riding Royal Garrison Artillery (ERRGA) was a part-time unit of Britain's Royal Artillery based at Hull in the East Riding of Yorkshire. It provided coastal defence artillery along the Humber Estuary from 1908 to 1956, manned siege batteries on the Western Front during World War I at the Somme and Ypres and played a role in the pursuit of the German army during the Hundred Days Offensive. It served as infantry in Allied-occupied Germany after World War II. Its successor units in the Territorial Army included anti-aircraft artillery and field engineers.
