Winifred Ashton CBE, better known by the pseudonym Clemence Dane, was an English novelist and playwright.

Regiment of Women is the debut novel of Winifred Ashton writing as Clemence Dane. First published in 1917, the novel has gained some notoriety due to its more or less veiled treatment of lesbian relationships inside and outside a school setting. It is said to have inspired Radclyffe Hall to write The Well of Loneliness.
