Cornelis Eliza Bertus Bremekamp was a Dutch botanist.
He received his education at the University of Utrecht, and performed as a botanical researcher in Indonesia and South Africa. In South Africa he collaborated with German botanist Herold Georg Wilhelm Johannes Schweickerdt.
From 1924 to 1931 he was a professor at Transvaal University in Pretoria, where he conducted studies of the genus Pavetta. During this time period he collected plants from northern Transvaal, Rhodesia, and Mozambique. A portion of his career was spent at the herbarium in Utrecht, where he specialized in studies of Rubiaceae and Acanthaceae.
The Acanthaceae genus Bremekampia and the Rutaceae species Toddaliopsis bremekampii are named in his honour.
