St Albans (/sɪnt ˈɔːlbənz/ ) is a suburb in Melbourne, Victoria, Australia, 17 km (11 mi) north-west of Melbourne's Central Business District, located within the City of Brimbank local government area. In the 2021 census, St Albans recorded a population of 38,042 people.

St Albans' main commercial and shopping precinct is located on Main Road West, Main Road East, Alfrieda Street, the railway station and East Esplanade. The postcode is 3021.

St Albans was first established as a township in 1887 and originally subdivided by the Cosmopolitan Land and Banking Company, who had acquired 512 hectares (5.12 km) in the hope of a quick financial gain during that period's land boom. Manager Alfred Padley made an arrangement with Victorian Railways to build the railway station, which he insisted be named St Albans after his maternal ancestors' association with St Albans Cathedral, England. Padley built and resided in Kieglo, which later became the Presbytery of the Sacred Heart . The company was later liquidated in 1903.

St Albans was promoted as an attractive location for professionals, providing easy rail access to central Melbourne and adjoining suburbs. St Albans Post Office opened on 22 October 1888.

St Albans became a small dormitory suburb for growing industrial firms in Deer Park and Sunshine. Despite the Great Depression, development was steady and, by 1940, around 700 people lived in the town. In the years following World War II, the population rapidly increased with the arrival of displaced migrants, particularly from Yugoslavia, Malta and Italy. This led to additional state schools and the 1953 establishment of Sacred Heart Catholic Church, as well as Greek, Russian and Serbian Orthodox churches.

St Albans remained geographically isolated from other suburbs by large areas of open land until the 1980s. It is now considered to be a middle-city suburb as the Melbourne Metropolitan area boundary now extends to over 35 km (22 mi) from the Melbourne CBD.

In the 2016 census, St Albans recorded a population of 37,309 people, 49.6% female and 50.4% male.

Great parks are located on the East and West borders of the suburb. These areas (particularly in the West) used to have large healthy populations of native reptiles, including Tiger snake, Eastern blue-tongued lizard and Eastern brown snake. Unfortunately due to development these species are now rarely seen in the area.

Due to development of the Cairnlea estate on the southern border of St Albans, native species of frogs have taken advantage and have taken up residence in the new wetlands and lakes. The Eastern Banjo Frog, common eastern froglet and even the now endangered growling grass frog have been seen and heard in the new wetlands and around Kororoit Creek.
