Manorburn Dam is a lake in the Central Otago district of the South Island of New Zealand, 3.5 kilometres (2.2 mi) east of Alexandra. Its outflow, the Manor Burn, connects with the Manuherikia River just to the northeast of the town.
The dam is also known as the Lower Manorburn Dam, as its inflow, also the Manor Burn, runs 25 kilometres (16 mi) northwest to it from the 700-hectare (1,700-acre) irrigation storage reservoirs Manorburn Reservoir, or the Upper Manorburn Dam, and Greenland Reservoir. Surrounded by schist tors, the lake is a popular spot for Alexandra's recreational activities. As determined by the Central Otago District Council, the lake is part of the 76-hectare (190-acre) Manorburn Dam Recreation Reserve.
