Henry William West (27 March 1917 – 5 February 2004) was a Northern Irish unionist politician who served as leader of the Ulster Unionist Party (UUP) from 1974 until 1979.

Career to Stormont

West was born in County Fermanagh and educated at Portora Royal School in Enniskillen. He worked as a farmer, taking an interest in local government, but it was not until 1954 that he entered Stormont as member for the Enniskillen seat, succeeding Thomas Nelson. In 1960 he was appointed Minister of Agriculture in the government of Lord Brookeborough, which he was to retain under the leadership of Terence O'Neill.

He became one of a number of Stormont MPs critical of O'Neill's conciliatory approach towards Nationalists and in 1969 he had the whip withdrawn, along with William Craig.
