Dale Spehr Baker (30 January 1939 – 27 March 2012) was an Australian politician, and was leader of the South Australian division of the Liberal Party of Australia from 1990 to 1992. He did not lead the Liberals to an election, but resigned from the leadership in 1992, and did not contest the subsequent leadership ballot.
Baker was the member for the south-eastern rural seat of Victoria (renamed MacKillop in 1993) from 1985 until 1997, when he unexpectedly lost his seat to independent Mitch Williams, who shortly joined the Liberal Party thereafter.
Baker had motor neurone disease and was a supporter of voluntary euthanasia. Baker died on 27 March 2012 from motor neurone disease.
