Yallourn, Victoria was a company town in Victoria, Australia built between 1921 and 1961 to house employees of the State Electricity Commission of Victoria (SECV), who operated the nearby Yallourn Power Station complex. However, expansion of the adjacent open-cut brown coal mine led to the closure and removal of the town in the 1980s. Whilst the township no longer exists, at the 2006 census, the adjacent region classified as Yallourn had a population of 251.

The State Electricity Commission of Victoria is a government-owned electricity company in Victoria, Australia. Originally established to generate electricity from the state's reserves of brown coal, the SEC gradually monopolised most aspects of the Victorian electricity industry, before being broken up and largely privatised in the 1990s. After several decades of dormancy, it was revived in 2023 to invest in renewable energy and storage markets.
