Albert Falls Dam is a dam in the Umgeni River, just outside Pietermaritzburg, KwaZulu-Natal, South Africa. Established in 1976, the dam has a gross capacity of 290.1 million cubic meters and a surface area of 23.521 square kilometres (9.082 sq mi). The dam wall is 33 metres (108 ft) high.

A lake-wide bloom of the dinoflagellate Ceratium hirundinella, discovered in Albert Falls Dam in October 2006, exposed a significant ecological change indicative of reduced water quality in this historically mesotrophic reservoir. The spatial distribution of the bloom was examined synoptically in October 2006 and in January 2007.
