San Rafael Lagoon is an arc-shaped coastal lake located in the Aisén Region of Chile, within the national park that bears its name. To the north the lagoon is connected to the Moraleda Channel, to the south lies the Ofqui Isthmus. To the west and east lie the Taitao Peninsula and the Northern Patagonian Ice Field respectively.

The Lagoon was formed by the retreat of the San Rafael Glacier in the Northern Patagonian Ice Field. Today it is a popular tourism destination, and ships sail from Puerto Chacabuco, Puyuhuapi and Puerto Montt to the lagoon nearly every day to see the ice falling from the glacier into the lagoon. Cruises pass by this area.
