Daniel Harris (c. 1761 – 13 June 1840) was an English builder, prison governor, civil engineer, and architect prominent in Oxford.
Harris's birthplace is obscure but he was born about 1761, as the entry in St-Peter-le-Bailey's register for his death in 1840 records his age as 79.
[3] Harris died at his home in New Road, Oxford in June 1840.
He developed a contracting business with convict labour, supplemented by hiring wage-earning tradesmen.
[5] Harris became involved in waterway engineering, starting by being the contractor to extend the Oxford Canal in Oxford from Hayfield Road to Worcester Street and build the Worcester Street wharves 1788–89.
