Catherine Impey (1847 – 14 December 1923) was a British Quaker activist against racial discrimination. She founded Britain's first anti-racist journal, Anti-Caste, in March 1888 and edited it until its last edition in 1895.
The journal was inspired by Booker T. Washington's Southern Letter. Impey visited the United States several times from 1878 and the journal focused largely on issues in America. In 1893, she formed an organisation, The Society for the Recognition of the Universal Brotherhood of Man, with the American Ida B. Wells, who visited the UK to campaign against lynching.
Impey lived in Street, Somerset.
