Keith William Anderson (23 October 1916 – 27 November 1965) was an Australian politician and member of the New South Wales Legislative Assembly from 1961 until 1962. He was a member of the Labor Party. The 1961 death of William Ferguson, the member for the seat of Paddington-Waverley, resulted in a by-election. Anderson won both the ALP pre-selection and the main election. However, his career lasted less than a year as the seat was abolished during a redistribution of the electorates before the 1962 election. He did not stand for another elected parliamentary position.
