The St. Francis River (French: Rivière Saint-François) is a river roughly 75 miles (120 km) long, which forms part of the Canada–United States border. The river rises (47°44′07″N 69°17′15″W / 47.7352°N 69.2874°W / 47.7352; -69.2874 (Rivière Saint-François source)) in a lake of the same name located 12 miles (20 km) east of the Rivière du Loup in Quebec. The portion that forms the boundary starts at the bottom of Lake Pohenegamook at the very northernmost point of New England between Estcourt Station, Maine, and Estcourt, Quebec. The river along the international boundary flows south and then south-east through two deep, narrow lakes to its mouth on the Saint John River at St. Francis, Maine/Saint-François-de-Madawaska, New Brunswick.

USS Bancroft (DD-256) became a Canadian ship as part of the Destroyers for Bases Agreement and was renamed after the St. Francis River to follow the Canadian tradition of naming destroyers after Canadian rivers while recognizing the shared national history of the ship.

Saint Francis River passes through Beau Lake on the border between Maine and Quebec. The river enters the north end of Beau Lake 15 miles (24 km) downstream of Lake Pohenegamook and leaves the south end of Beau Lake 13 miles (21 km) upstream of the Saint John River confluence. Beau Lake is one of the deepest lakes in northern Maine. The lake is ideal habitat for lake trout, brook trout, and land-locked Atlantic salmon; but these species are in competition with a large population of yellow perch, and muskellunge are migrating into the lake from downstream.

Saint Francis River passes through Glazier Lake on the border between Maine and New Brunswick. The river enters the north end of Glazier Lake 3 miles (4.8 km) downstream of Beau Lake and leaves the south end of Beau Lake 4 miles (6.4 km) upstream of the Saint John River confluence. Tributaries to the lake include Yankeetuladi Brook on the Maine side, and Canadian Tuladi Brook on the New Brunswick side. Glazier Lake is deep and narrow similar to Beau Lake, and offers similarly suitable habitat for lake trout, brook trout, salmon, and muskellunge.
