Frankston is an outer-suburb of Melbourne in Victoria, Australia, in the local government area of the City of Frankston. It is located 41 km south-east of the Melbourne city centre, at the northernmost point of the Mornington Peninsula. Due to its geographic location, it is often referred to as "the gateway to the Mornington Peninsula".
European settlement of Frankston began around the same time as the foundation of Melbourne in 1835—initially as an unofficial fishing village serving the early Melbourne township. Prior to its settlement, the Frankston area was primarily inhabited by the Mayone-bulluk clan from the Bunurong tribe of the Kulin nation. The official village of Frankston was established in 1854, with its first land sales taking place on 29 May. It has subsequently given its name to the broader Frankston local government area since 1893, and serves as both its activity and administrative centre.
Situated on the eastern shoreline of Port Phillip, Frankston has been a popular seaside destination of Melbourne since the 1880s. Frankston Beach is still one of the most frequented in Victoria, and is recognised as one of the cleanest in Australia. It is also home to one of the largest exhibitions of sand sculpting in the Southern Hemisphere.
