Donald Leslie Chipp, AO (21 August 1925 – 28 August 2006) was an Australian politician who was the inaugural leader of the Australian Democrats, leading the party from 1977 to 1986.
He began his career as a member of the Liberal Party, winning election to the House of Representatives in 1960 and serving as a government minister for a cumulative total of six years.
Chipp left the Liberals in 1977 to help create a new party, the Democrats, and famously promised to "keep the bastards honest".
He won election to the Senate later that year, and led the party at four federal elections; after 1983 it held the sole balance of power in the Senate.
