Thomas Holcroft (10 December 1745 – 23 March 1809) was an English dramatist and miscellaneous writer.
He was born in Orange Court, Leicester Fields, London. His father had a shoemaker's shop, and kept riding horses for hire; but having fallen into difficulties was reduced to the status of hawking peddler. The son accompanied his parents in their travels, and obtained work as a stable boy at Newmarket, where he spent his evenings chiefly in miscellaneous reading and the study of music. Gradually he obtained a knowledge of French, German and Italian.
