The Electoral district of Frankston is an electoral district of the Victorian Legislative Assembly. It currently includes the suburbs of Frankston and Frankston South south east of Melbourne. The electorate was first created prior to the 1967 election and the Liberal Party held the seat until the Cain landslide of 1982. Population increases, however, meant the seat was abolished in 1985 and replaced by two electorates—Frankston South and Frankston North.
