George T. Day (1822–1875) was a Free Will Baptist writer, publisher, pastor and professor.
Day worked in textile mills as a child, and his parents moved to Scituate, Rhode Island, and then Hebronville in Massachusetts.
After his mother died when he was twelve, Day went to live with a brother in Lonsdale, Rhode Island, where he attended a revival and was later baptized by Martin Cheney in Olneyville in 1840.
He then went to Maine, and returned to Rhode Island to study at the Smithville Seminary in Scituate.
Day continued working extensively with The Morning Star until his death in 1876 at his sister's house in Providence, Rhode Island.
