James Dumaresq (c. 1792–1841) was a merchant and fisherman who was the first known resident of L'Anse au Cotard near L'Anse-au-Clair, in Newfoundland and Labrador, Canada.
Dumaresq was the first of many Jersey fisherman and merchants to travel to the region now known as the Jersey Trail.
He was part of the patrician Dumaresq family of Jersey, and a descendant of Elias Dumaresq, 3rd Seigneur of Augrès through his paternal grandfather Captain William Dumaresq.
[3] James Dumaresq landed in L'Anse au Cotard around 1810, where he would build his home.
In 2004 archaeological research was done in the region and the home of James Dumaresq was discovered.
