Located on the south side of Trinity Bay is the community of Heart's Delight-Islington. Legend has it that Heart's Delight was given its name by a traveller who arrived in the cove and found his "Heart's Delight" there. However, others have suggested that Heart's Delight and the communities of Heart's Desire and Heart's Content farther to the north were named after fishing vessels, the Heart's Delight, the Heart's Desire and the Heart's Content, that fished out of these harbours during the migratory fishery in the seventeenth and eighteenth centuries.

Heart's Delight was settled in the late 1700's as the population expanded south along the coast from places such as Old Perlican, New Perlican and Heart's Content, that were first settled in the seventeenth century, and as new settlers arrived from the English west country.. The earliest reference to Heart's Delight in the Trinity parish records is the birth of Elizabeth Wolfrey, daughter of William and Elizabeth, in 1785.

Islington, immediately south of Heart's Delight, was originally called Island Cove but the name was later changed to Islington after a village in England. The communities of Heart's Delight amalgamated and were incorporated in 1973.
