Prince Edward Island Route 15 is a secondary highway in central Prince Edward Island.
Route 15 follows Brackley Point Road beginning at the junction with the Charlottetown Perimeter Highway (Trans-Canada Highway, Route 1). The route passes near the Charlottetown Airport, then proceeds north through the community of Brackley Beach. It is co-signed with Route 6 for south of Brackley Beach. Route 15 terminates at the north shore, turning east and becoming the un-numbered Gulf Shore Parkway.
Until the 1990s, Route 15 began at an intersection with Route 2 (St. Peters Road) in Charlottetown, south of the current terminus. When the Charlottetown Perimeter Highway was constructed, Route 2 was reassigned to the new road, and the Route 15 designation was dropped from Brackley Point Road south of the new ring road.
