town (parish), Huntingdonshire district, administrative county of Cambridgeshire, historic county of Huntingdonshire, England, on the north bank of the River Ouse. It was originally a village called Slepe. St. Ives was granted an eight-day fair by Henry I in 1110 and developed in consequence until the fair was suspended during the Black Death (1349). A six-arched bridge (c. 1415), with a chapel over the central pier, spans the Ouse. Pop. (2001) 16,001.

town (“parish”), Penwith district, administrative and historic county of Cornwall, England. In 1497 the pretender Perkin Warbeck was proclaimed king when he anchored in St. Ives harbour. Clustered around the harbour is the old town of winding cobbled streets and colour-washed stone cottages. Fishing and tin mining were important until the late 19th century; since then the mild climate and sandy beaches—particularly Porthmeor Beach, which is popular with surfers—have attracted vacationers, and tourism has become the economic base. In the early 20th century the town emerged as an artist colony, and it continues to be a centre for art. The Tate St. Ives (1993), a branch of the national Tate galleries, is located there and includes the Barbara Hepworth Museum and Sculpture Garden. The name St. Ives has been given to a style of pottery established there by Bernard Leach in 1920. Pop. (2001) 16,001.
