Bright is an electorate for the South Australian House of Assembly. It is named after Charles Bright, at various times South Australian Supreme Court Judge, Flinders University Chancellor, Health Commission Chairman, and Electoral Boundaries Commission Chairman. The seat covers southern coastal suburbs of Adelaide including Brighton, North Brighton, South Brighton, Hallett Cove, Hove, Kingston Park, Marino, Seacliff, Seacliff Park, and part of Somerton Park.

The electorate was created at the 1983 redistribution, to replace the abolished seat of Brighton, as a marginal Liberal seat with a notional one percent two-party margin. However, it was won by the Labor's Derek Robertson at the 1985 election, before being won by Liberal Wayne Matthew at the 1989 election. He held the seat until his retirement at the 2006 election. Liberal shadow minister Angus Redford left the South Australian Legislative Council to contest the seat but was defeated by Labor's Chloë Fox from a 14.4 percent swing, the largest in the state, amidst a statewide landslide averaging a 7.7 percent swing. The Liberals picked up a 6.2 percent swing at the 2010 election, just short of picking up the seat, with Labor retaining the seat on a 0.4 percent margin, making Bright Labor's most marginal seat following the election. Liberal David Speirs won the seat from a 3.7 percent swing at the 2014 election.
