Swanpool is a small lake behind a shingle bar, separating it from the beach of the same name, near Falmouth, on the south coast of Cornwall, UK. It is between Maenporth and Gyllyngvase, on the South West Coast Path. There was formerly a mine extending beneath the lagoon.

It is approximately one mile from the town centre, and is perhaps the quietest district of Falmouth. The area is largely occupied by tourist accommodation. A notable building in the area is Swanpool House, a 19th century building which was occupied by American forces during the Second World War but is now in use as holiday apartments.
