Dorothea Frances Bleek (later Dorothy F. Bleek; born 26 March 1873, Mowbray, Cape Town – died 27 June 1948, Newlands, Cape Town)[1][2] was a South African-born German anthropologist and philologist known for her research on the Bushmen (the San people) of Southern Africa.

The work of Dorothy Bleek was largely a continuation of her father and aunt's research, but she also made numerous notable contributions of her own to the field.

Her culminating work, published after death, was the book A Bushman Dictionary, still referenced today.

This is in the introduction to The Heart of the Hunter (1961), a follow-up to The Lost World of the Kalahari, the book based on the BBC series that brought the Bushmen to international attention.

Bleek's research and findings are often overshadowed by the work of her father, and she has been criticised for lacking the empathy and intuition of him and her aunt.
