Delacombe is a large and rapidly growing industrial/residential suburb on the south west rural-urban fringe of Ballarat, Victoria, Australia. The population at the 2016 census was 6,297 making it the sixth most populated in the Ballarat urban area.
Delacombe forms a large part of the Ballarat West Growth Area where suburban development is encouraged by the City of Ballarat and State Government of Victoria. Much of the city's planned subdivision for new housing estates is happening in Greenfield land in and around the suburb and it is predicted to be home to over 12,000 residents in 2030.
The suburb is built upon the floodplain of the Winter Creek. Its tributaries are stormwater drains, including the Banyule.
It is one of the few Ballarat suburbs with its own shopping centres and a future activity centre for the suburb is planned by the City of Ballarat.
It is named in 1965 after the then incumbent Governor of Victoria, Sir Rohan Delacombe.
