Waite is an electoral district of the House of Assembly in the Australian state of South Australia. Named after Peter Waite, a 19th entrepreneur and philanthropist in the current area of the electorate, it is a 33.1 km² urban electorate in Adelaide's inner south-east, taking in the suburbs of Brown Hill Creek, Clapham, Hawthorn, Kingswood, Lower Mitcham, Lynton, Mitcham, Netherby, Panorama, Pasadena, Springfield, St Marys, Torrens Park, Urrbrae and Westbourne Park as well as parts of Belair, Colonel Light Gardens, Daw Park and Leawood Gardens.
Waite was created in the 1991 electoral distribution as a safe Liberal seat, replacing the abolished district of Mitcham, the only single-member lower house seat anywhere throughout Australia to be won by the Democrats. Waite was first won at the 1993 election by Liberal treasurer and deputy-premier Stephen Baker. Upon his retirement at the 1997 election, he was succeeded by Liberal Martin Hamilton-Smith, who became an independent two months after the 2014 election.
