Lake Roxburgh is an artificial lake, created by the Roxburgh Dam, the earliest of the large hydroelectric projects in the southern South Island of New Zealand.

It lies on the Clutha River, some 160 km (99 mi) from Dunedin.

The town of Roxburgh lies 5 kilometres (3.1 mi) south of the Dam.

Lake Roxburgh Village is described by Statistics New Zealand as a rural settlement.

Although some people chose not to answer the census's question about religious affiliation, 59.3% had no religion, and 37.0% were Christian.
