Terence Bay Harbour is a marina and boat launch situated on Terence Bay River in the rural fishing community of Terence Bay, Nova Scotia, within the Halifax Regional Municipality. The site sits at approximately 44° 28' N, 63° 42' W on the Chebucto Peninsula.

A public boat ramp at Terence Bay River Park, accessible from Terence Bay Road, allows paddlers and boaters to put in directly on the river.

The inner portion of the bay is a popular area for kayaking and recreational boating, with Sandy Beach serving as a commonly noted boundary for safe paddling; conditions beyond that point can be hazardous.

The river and surrounding waters are also frequented by anglers targeting brook trout, Atlantic pollock, and other species.
