The Melbourne Mint, located on the corner of William and La Trobe Streets in Melbourne, Australia, was first established as a branch of the British Royal Mint, opening in 12 June 1872. The main building houses the administration offices, as well as the living quarters for the Deputy Master, his family and domestic servants in the right hand section. There is a pair of guard houses, one by each gate, and the assay and smelting works were in a range of buildings behind. It minted gold sovereigns from 1872 until 1931, and half-sovereigns (intermittently) from 1873 until 1915. In 1916 it commenced minting Commonwealth silver threepences, sixpences, shillings and florins. From 1923 it minted all pre-decimal denominations. It minted rarities such as the 1921/22 overdate threepence, 1923 half-penny and 1930 penny, as well as Australia's four commemorative florins in 1927 (Canberra), 1934/35 (Melbourne Centenary), 1951 (Federation Jubilee) and 1954 (Royal Visit). It assisted the Royal Australian Mint in Canberra in producing one cent coins from 1966 to 1968 and two cent coins in 1966. From 1969 all coin production moved to the Royal Australian Mint in Canberra, and the building housing the coin minting equipment was demolished shortly afterwards. The remaining administrative building became the home of the Royal Historical Society of Victoria, as well as the civil marriage registry, with many weddings in the large ground floor room. Since 1998 it has been vested in a self funded-government body that manages a number of former government buildings, and it has hosted a range of tenants.

The former Royal Mint is and is of architectural significance as one of the finest 19th century government buildings in Australia, in a restrained Renaissance revival style. It was designed by Public Works Department architect J.J Clark, best known for the equally significant Old Treasury Building, Melbourne. The facade design has been said to be based on Renaissance Palazzi, such as the paired piaster arrangement of the Palazzo Vidoni-Caffarelli, Rome (1515) attributed to Raphael, or the paired Ionic columns of the Palazzo Corner della Ca' Grande, Venice, by Sansovino (1545).

The colourful coat of arms placed on the front gates in mid-twentieth century were by the Melbourne woodcarver Walter Langcake. The original design, based on Queen Victoria's coat of arms, is adapted especially for a British Royal Mint branch office in colonial Victoria. The supporting animals are not crowned and a maned horse replaces the usual unicorn.

From 2007 the former Mint became the home for the Hellenic Museum, showcasing Greek art, history and culture.

From October 2012 private company, Melbourne Mint Pty Ltd, was situated on the ground level and level one of the Melbourne Mint building. Melbourne Mint Pty Ltd belongs to a group of Australian precious metals companies which include Australian Bullion Company (ABC), Gold Merchants International (GMI) and Melbourne Mint Coins. It has no historical relationship to the original Royal Mint.
