It is named for English aristocrat Sir Thomas Smith or Smythe (1558–1625).
It is located in the northeast of the main island, at the southern end of Harrington Sound, the large lagoon close to the main island's northeastern tip.
As with most of Bermuda's parishes, it covers just over 2.3 square miles (about 6.0 km² or 1500 acres).
[1] Natural features in Smith's include Spittal Pond, John Smith's Beach, Devil's Hole, Gibbet Island, and Portuguese Rock.
Despite this, his contribution to his stake in the colony was minimal, and the area was briefly known as "Harris' Bay".
