Westminster was a provincial electoral district in the Canadian province of British Columbia. It appeared in the 1890 election only. In 1894 it was succeeded by Westminster-Chilliwhack, Westminster-Delta, Westminster-Dewdney, and Westminster-Richmond, which were in the 1898 election succeeded by ridings named similarly, but without the "Westminster".
NB This provincial riding is not to be confused with the federal Westminster District riding which appeared only in the 1917 election (it was succeeded by the Fraser Valley riding.
In the early 1880s the Lower Fraser Valley south and east of the city of New Westminster was largely unpopulated, with voters there voting in one of the two New Westminster ridings (New Westminster or New Westminster City). With the opening of the Canadian Pacific Railway settlement of the lush Fraser Valley lands was rapid, and a new more rural riding - Westminster - was created spanning the entire lower Fraser from Richmond to Chilliwack. Increasing growth led to the riding's further subdivision for the 1894 election into four sub-ridings, Westminster-Chilliwhack, Westminster-Delta, Westminster-Dewdney and Westminster-Richmond. The successor ridings dropped the Westminster-prefix for the 1903 election.
