William Clark Haines (10 January 1810 – 3 February 1866),[1] Australian colonial politician, was the first Premier of Victoria.

He was educated at Charterhouse School and Caius College, Cambridge,[2] where he graduated in medicine; he later practiced surgery for several years.

Haines migrated to the Port Phillip District (later Victoria) in 1841 and settled in the Geelong area.

[3] The historian Raymond Wright describes Haines as a bluff, plain "honest farmer" type, who was "much enjoyed for his appalling public speaking."

A bill was introduced to enlarge the Assembly, redraw electoral boundaries and abolish the property qualification for both votes and candidates.
