The Steart Peninsula () is a peninsula in Somerset, England. At its outermost tip is Fenning Island (now joined to the mainland), at the tip of which is Stert Point (sometimes spelt Steart Point) which is the eastern end of the West Somerset Coast Path. North of Stert Point lies Stert Island, which was joined to the peninsula until about 1798. The peninsula consists largely of low-lying flat farmland, and projects northwards on the west side of Stockland Reach, the lower stretches of the estuary of the River Parrett.
