Westminster-Delta was a provincial electoral district in the Canadian province of British Columbia from 1894 to 1900. It and its sister ridings Westminster-Chilliwhack, Westminster-Dewdney and Westminster-Richmond were successors to the four-member Westminster riding, which appeared in 1890 only and was a subdivision of the older New Westminster (provincial electoral district) riding. Westminster-Delta was succeeded by the Delta riding in the election of 1903.
