William Robert Ogilvie-Grant

William Robert Ogilvie-Grant (25 March 1863 – 26 July 1924) was a Scottish ornithologist.

Ogilvie-Grant was educated at Cargilfield Preparatory School and Fettes College, Edinburgh, where he studied zoology and anatomy. In 1882 he became an Assistant at the Natural History Museum. He studied ichthyology under Albert C. L. G. Günther, and in 1885 he was put in temporary charge of the Ornithological Section during Richard Bowdler Sharpe's visit to India. He remained in that department, eventually becoming Curator of Birds from 1909 to 1918.

He also succeeded Bowdler Sharpe as editor of the Bulletin of the British Ornithologists' Club, a post he held from 1904-1914.

Ogilvie-Grant made many collecting trips, especially to Socotra and the Madeira and Canary islands.
