Delph Locks or the Delph Nine are a series of eight (originally nine) narrow canal locks on the Dudley No. 1 Canal in Brierley Hill, in the West Midlands, England. They were opened in 1779, and reopened in 1967 following restoration of the Dudley Canal and the Stourbridge Canal in a joint venture between the Staffordshire and Worcestershire Canal Society and the British Waterways Board.
