Old Grimsby (Cornish: Enysgrymm Goth)[1] is a coastal settlement on the island of Tresco in the Isles of Scilly, England.

[3] The northern part of the settlement is (now usually historically) known as Northward (or Norrard).

[2] The island's community centre is located here, and adjacent to it is the primary school for Tresco and Bryher.

To the southwest, on the road to New Grimsby, is the hamlet of Dolphin Town, where the island's parish church is located (St Nicholas's Church).
