Gorleston-on-Sea, historically and colloquially known as Gorleston, is a seaside town in the borough of Great Yarmouth in Norfolk, England. It lies to the south of Great Yarmouth, on the opposite side of the mouth of the River Yare. Historically in Suffolk, it was a port town at the time of the Domesday Book. It was incorporated into Great Yarmouth in 1836. Gorleston's port became a centre of fishing for herring along with salt pans used for the production of salt to preserve the fish. In Edwardian times the fishing industry rapidly declined and the town's role changed to that of a seaside resort.

William George Fleming GC (1865–1954) was a lifeboatman from Gorleston-on-Sea on the east coast of Norfolk, England. His service with the Royal National Lifeboat Institution (RNLI) spanned nearly fifty years, in which time he won the George Cross and the RNLI Medal in Gold and in Silver, and the Bronze Medal three times.
