May Sinclair was the pseudonym of Mary Amelia St. Clair (24 August 1863 – 14 November 1946), a popular British writer who wrote about two dozen novels, short stories and poetry. She was an active suffragist, and member of the Woman Writers' Suffrage League. May Sinclair was also a significant critic in the area of modernist poetry and prose, and she is attributed with first using the term stream of consciousness in a literary context, when reviewing the first volumes of Dorothy Richardson's novel sequence Pilgrimage (1915–67), in The Egoist, April 1918.
