Gloucester was a provincial electoral district for the Legislative Assembly of New Brunswick, Canada from the 1828 election of the 9th New Brunswick Legislature.

It mirrored Gloucester County, and used a bloc voting system to elect candidates.

It was abolished with the 1973 electoral redistribution, divided up into five first past the post districts: Caraquet, Nepisiguit-Chaleur, Nigadoo-Chaleur, Shippagan-les-Îles and Tracadie.
