Doug Woolerton (born 17 May 1944) is a New Zealand politician who has been a member of the New Zealand First party since it was founded, and the National Party for a few years before that.

He was educated at Hamilton Boys' High School, and has a background in agriculture, having been a farmer for twenty-one years and director of a milk company for nine.

Woolerton was originally a member of the National Party. He stood for selection as the National candidate for the seat of Hamilton West in 1990, but lost to Grant Thomas, who was later elected to the seat. Woolerton left the National Party in 1992 to form the New Zealand First party with Winston Peters.

Woolerton first entered Parliament in the 1996 election, becoming a list MP after being ranked fifth on the New Zealand First party list. He remained an MP until his party lost all parliamentary seats in the 2008 general election.

He was the president of New Zealand First from the party's inception until 2005 when he resigned in protest against Winston Peters taking a visible role in the Labour-led government as Minister of Foreign Affairs. Later there were frictions between then New Zealand First president Dail Jones on the one hand, and Woolerton and Brian Donnelly on the other, over the latter's support for Sue Bradford's private members bill to outlaw parental corporal punishment of children (or smacking).^[1]
