Heart's Delight-Islington is a town on the south side of Trinity Bay in the Canadian province of Newfoundland and Labrador, located on Newfoundland and Labrador Route 80.

Local tradition maintains that the community was given its name by weary travellers who were "delighted" by the beauty of the place.

The first settler is believed to have been a man named Bryant, and the first official Census in 1836 recorded a population at 167, 165 Protestant Dissenters and two Roman Catholics.
