Little Sunapee Lake (or "Little Lake Sunapee", a frequent local usage) is a 472-acre (1.91 km2) water body located primarily in Merrimack County in central New Hampshire, United States, in the town of New London. A small portion of the lake crosses into neighboring Springfield in Sullivan County. The lake is sometimes referred to as "Twin Lakes" due to a long, narrow peninsula which nearly cuts the lake in half. Water flowing out of the lake passes through Goose Pond and Otter Pond before entering Lake Sunapee. Bucklin Beach is a town of New London recreation area at the east end of the lake.
