Colton is an electoral district of the House of Assembly in the Australian state of South Australia. It is a 15.5 km² urban electorate on Adelaide's western beaches, taking in the suburbs of Fulham, Fulham Gardens, Henley Beach, Henley Beach South, Kidman Park as well as parts of Grange, Lockleys and Seaton.

The electoral district is named after Mary Colton, who arrived in Adelaide in 1839 and worked for the welfare of women and children. She was the President of the Women's Suffrage League, and lived to see the introduction of equal voting rights for women in 1895.

Colton was created to replace the abolished seat of Henley Beach in the 1991 electoral distribution as a notionally marginal Liberal seat. It was first contested at the 1993 election, where it was won in a large swing to the Liberals by former Adelaide City Council Lord Mayor Steve Condous, recording a 60.5 percent two-party vote from a 9.5 percent two-party swing. This was reduced at the 1997 election to 54 percent, and upon Condous' retirement at the 2002 election, it was won by Paul Caica for Labor with a 54.6 percent two-party vote, which increased to 66.3 percent at the 2006 election. This was reduced to 54 percent at the 2010 election and 51.5 percent at the 2014 election.
