Mount Eliza is a seaside suburb on the Mornington Peninsula in Melbourne, Victoria, Australia, 42 km (26 mi) south-east of Melbourne's Central Business District, located within the Shire of Mornington Peninsula local government area. Mount Eliza recorded a population of 18,734 at the 2021 census.

The traditional Boonwurrung name for the mount is Berringwallin. The mount was given its European name in 1836 after Captain William Hobson’s wife, Eliza Elliott.

Prior to large scale subdivision, Mount Eliza was mainly a location for holiday homes, with the Mount Eliza Post Office opening on 15 November 1920. This began to change in the early half of the 20th century when many old estates were subdivided. One such subdivision was Ranelagh Estate, designed by Walter Burley Griffin and Marion Mahony Griffin in 1924 in tandem with the surveyors Tuxen and Miller.

Daveys Bay was named after James Davey who constructed a jetty in the 1840s to ship his produce to Melbourne. In 1909 the Daveys Bay Yacht Club was established, and winds its way to a walking track overlooking Mt Eliza Beach on the shores of Canadian Bay, which was named after three Canadians who owned a sawmill in the area in the 1950s. In 1928, the independent girls school Toorak College was built and is one of the oldest independent girls schools in Victoria. By the 1950s the shopping precinct began to develop and by the 1960s was a well established shopping village. Hollywood glamour came to Mt Eliza in 1959 when movie stars Fred Astaire, Gregory Peck and Ava Gardner arrived to shoot the Stanley Kramer film, On The Beach, based on the novel of the same name by British novelist Nevil Shute who had lived at nearby Langwarrin.

Adjacent to Sunnyside beach sits a historical property Morning Star Estate. Morning Star Estate is a distinctive example of a Victorian era mansion built as a rural or holiday retreat on the Mornington Peninsula, it incorporates a number of architectural styles – including Tudor and Gothic Revival.

Sunnyside estate (now Morning Star Estate) was originally purchased by Londoner Francis Alfred Gillett in 1865 a short time after he arrived in the colony in 1853. Gillett designed the Sunnyside mansion sometime around 1867–1870. In 1932 the property was purchased, with funds from a bequest, by the Catholic Church and became known as Morning Star Boys' Home. The boys’ home was developed into a country-training centre for delinquent boys, giving them exposure to the benefits of rural life. The boys later became involved in an extensive building program, which led to further developments of the property. Despite this, the mansion remained the dominant architectural feature of the property.

Renovations and extensions were undertaken by the Franciscans in 1944–1946. Some effort to follow the lead of the mansion was made in the external Tudor/Gothic detailing of the large chapel. A number of courtyards were formed by the new buildings, including a large courtyard which was used for sports and was later enclosed. The remains of a football field lie to the south of the building complex, and a tall angular concrete pillar near the Nepean Highway originally carried a statue of the Virgin Mary sculpted by one of the brothers.

Morning Star Estate has been in a number of films due to its location and historical buildings, including a three-month location shoot around the mansion for the movie Partisan, starring French actor Vincent Cassel, during 2013 and 2014. The mansion was also the location for the Kath & Kim movie spin-off Kath & Kimderella.

Morning Star estate is also home to possibly the largest rose garden in Victoria, and the gardens surrounding the main mansion are home to more than 700 varieties of ornamental roses.

The suburb is bordered by Kackeraboite Creek, Humphries Road, Moorooduc Highway, Wooralla Drive, the Mornington railway line, Oakbank Road, Manyung Creek and Port Phillip.

There are several beaches and bays located in Mount Eliza, which include Canadian Bay (has had the name since the late 19th Century), Daveys Bay, Half Moon Bay, Moondah Beach, Ranelagh Beach and Sunnyside North Beach. In addition Mount Eliza is also home to the Moorooduc Quarry Flora and Fauna Reserve and several creeks including Ballar Creek, Earimil Creek (formerly Dennant Creek), Gunyong Creek, Kackeraboite Creek, Manmangur Creek and Manyung Creek (named after the Manyung Fault).

The suburb’s main shopping area is known as Mount Eliza Village. It is situated at the intersection of Canadian Bay Road and Mount Eliza Way.
