Alma Harbour is a boat ramp access point on the Upper Salmon River in New Brunswick, situated within or near Fundy National Park.

The site serves as a practical launch point for paddlers and boaters exploring the river, and a bridge at the harbour serves as a notable landmark — a Fisheries and Oceans Canada rotary screw trap for Atlantic salmon monitoring is operated approximately 1.

6 kilometres upstream from the Alma Harbour bridge each spring.
