The electoral district of Marodian was a Legislative Assembly electorate in the state of Queensland. It was first created in a redistribution ahead of the 1950 state election, and existed until the 1960 state election. Marodian was centred on Gayndah and Goomeri, and incorporated parts of the former Isis and Wide Bay electorates. It was named for Marodian Station, situated between Kilkivan and Brooweena. It replaced the Wide Bay electorate due to confusion between the previous state seat and the federal Division of Wide Bay.
