South Yarra is an inner-city suburb located in Melbourne, Victoria, Australia, situated four kilometers south-east of the Central Business District. It occupies a strategic position within the local government areas of the Cities of Melbourne and Stonnington. Punt Road serves as the primary dividing line between these two administrative regions, with the eastern side falling under Stonnington and the western side under Melbourne. This geographic placement defines its character as a dense, urban residential and commercial hub.

The area was originally inhabited by the Yalukit-willam clan of the Boonwurrung people before being settled by British colonists in the late 1830s. The first Crown land sale occurred in June 1840, attracting wealthy purchasers who established large houses, making it a popular suburban retreat for Melbourne's elite. During the 1920s and 1930s, many mansion gardens were subdivided for flats, and by the mid-twentieth century, apartment construction continued around the railway station, transforming it into one of Melbourne's most densely populated suburbs.

The suburb is defined by its upmarket shopping districts along Toorak Road and Chapel Street, which feature trendy retail, dining, and nightlife. The area centered on Commercial Road historically served as a gay village. Architectural heritage is prominent, with numerous registered mansions like Como House and Poolman House, alongside Victorian terraces on Park Street and Art Deco apartments in the Domain Precinct. The Jam Factory and the Como Centre stand as major commercial landmarks within this historic landscape.

Cultural appeal is driven by the Prahran Market, one of Melbourne's most popular fresh produce markets, and a vibrant cafe culture. Religious heritage is marked by the Melbourne Hebrew Congregation synagogue, the largest in Australasia, and Christ Church on Toorak Road. Public spaces include part of the Royal Botanic Gardens and Fawkner Park, offering recreational facilities and grand avenues. The area retains a reputation for exclusivity and high-end living, supported by its concentration of heritage buildings and upscale amenities.

South Yarra recorded a population of 25,028 at the 2021 census, reflecting its status as a densely populated urban center. Transport infrastructure includes South Yarra and Hawksburn railway stations, serving multiple lines, along with tram routes 58, 72, and 78. The economy is heavily influenced by its role as a premier shopping and dining destination. Its central location and extensive public transport links make it a key component of Melbourne's inner-city residential and commercial fabric.
