Ince Castle (Cornish: Kastel Enys) is three miles (5 km) from Saltash in Cornwall, England, UK.

Henry Killigrew, the Royalist MP for West Looe, who modified the first house in about 1642, kept four wives, one in each tower, each unknown to the others, according to tradition.

The owner from 1922 to 1937 was H. R."Bobby" Somerset, whose yacht, Jolie Brise, was a multiple winner of the Fastnet Race and was kept in the boathouse at Ince Castle.

Ince's next occupants were Scottish yachtsman James Bryce Allan (1893-1960) and his wife, stage and silent screen actress Rita Jolivet.

About this time, the lower floor French windows were installed to bring more light into the house and the service wing was extended.

In October 2018 the house was sold for £7 Million (Source land Registry £7,000,030 Oct 31 2018) to a South African.
