Clattice Harbour, also sometimes known as Clattis Harbour, is an abandoned community located in the province of Newfoundland and Labrador. A fisherman named Culliton and a Connors family settled the natural harbour in the early 1800s to prosecute the local herring fishery and gain access to local timber stocks. By 1871, the population grew to 71 due to the settlement of various Brewer, Carroll, Follett, Hepditch, and Palfrey families.
