Stanley George "Stan" Evans (born 14 July 1930) is a former South Australian Liberal politician.He was the member for Onkaparinga from 1968 to 1970, then Fisher from 1970 to 1985.A 1983 electoral redistribution turned Fisher into a marginal seat, with much of the old Fisher moving into the safe Liberal seat of Davenport. Evans failed to win Liberal pre-selection for Davenport, but stood as an Independent Liberal at the 1985 election and won the seat, temporarily forcing Dean Brown out of politics.He nevertheless maintained his Liberal Party membership, as the Liberals did not at that time have a policy for expelling members who opposed endorsed candidates. He then stood in the 1989 election as the endorsed Liberal candidate for Davenport. He retired at the 1993 election, allowing his son Iain Evans to take the seat.
