Beatrice Mary Blackwood (3 May 1889 – 29 November 1975) was a British anthropologist, who ran the Pitt Rivers Museum in Oxford from 1938 until her retirement in 1959.

Women were not allowed to official matriculate or graduate from Oxford until 1920,[2] at which time Ms. Blackwood took both the BA and MA in the same day.

In 1924, Blackwood travelled to North America on a Laura Spelman Rockefeller Fellowship to study anthropology in Native American, African-American, Asian and Caucasian societies.

[2] A year later, she received funding from Yale University, the Oxford Committee for Anthropology and the National Research Council and traveled to New Guinea for 18 months, where she worked in the Northern Solomon Islands.

This research was eventually published by Oxford University Press in an ethnography entitled Both Sides of Buka Passage, in 1935.
