Route 776 is a provincial highway in New Brunswick, Canada.

It serves as the main road on Charlotte County's Grand Manan Island, following the entire eastern coast of the island.

The northern terminus of Route 776 is at the Coastal Transport Limited ferry terminal at the top of Ferry Wharf Road in the community of North Head.

The southern terminus is at Southwest Head at the Southwest Light, a Canadian Coast Guard light station atop 300-foot (91 m) cliffs.

The community of Ingalls Head is the only major population centre on Grand Manan Island not having direct access to Route 776; one must drive down Ingalls Head Road in Grand Harbour to access this village.
