Lake Ohau is a glacial lake in the Mackenzie Basin of New Zealand's South Island. It is fed by the Hopkins and Dobson rivers, which have their headwaters in the Southern Alps, and has its outflow in the Ohau River, which itself feeds into the Waitaki River hydroelectric project.

Lake Ohau is on the route of the Alps to Ocean Cycle Trail, which has been constructed in the years after approval in 2010. The trail runs along the Lake up to Lake Ohau Lodge, and then climbs up the Tarnbrae Track before a flowing descent to Quailburn Road.
