Devils Island, Nova Scotia is located on the northeast entrance of Halifax Harbour off the coast of the community of Eastern Passage, part of the Halifax Regional Municipality.

[1] The first permanent settlement on this 12-hectare (30-acre) island was established in 1830, and by 1850 there were three houses and a school.

A number of Devil's Island residents, notably Ben Henneberry, provided valuable folklore to pioneering Canadian folklorist Helen Creighton.

The island is currently owned by Halifax entrepreneur Bill Mont.

The island was also the base for a rescue lifeboat until the 1950s which saved the crews of many vessels stranded on the shoals approaching Halifax Harbour.
