Harrington Sound is a large inland lake in the northeast of the main island of Bermuda. It is surrounded by the main island on all sides, only appearing open to the ocean via a small channel called Flatt's Inlet in the southwest. Much of the sound's water flows to and from the ocean via subterranean cavern systems, notably Crystal Cave and Leamington Cave.

Harrington Sound is surrounded by the parishes of Smith's, Hamilton, and St. George's. It is well known for fishing, swimming, sailing and kayaking.

The sound was named for Lucy Harrington, Countess of Bedford. It is the lowest point on the Bermuda sea platform, being over 20 metres deep at its deepest in the southeast. Its geological origins are uncertain, though it is not (as it appears to some) a volcanic crater. There are numerous small islands in the sound, notably Trunk Island.

Unfortunately, as Bermuda's human population (and fishing) has increased there has been an equivalent drop in the populations of the sound's formerly abundant shellfish.
