Mount Barker is a city in South Australia. Located approximately 33 kilometres (21 miles) from the Adelaide city centre, it is home to 25,026 residents (2021). It is the seat of the District Council of Mount Barker, the largest town in the Adelaide Hills. It is part of Greater Adelaide, alongside being one of the fastest-growing areas in the state.

Mount Barker lies at the base of a local eponymous peak called the Mount Barker summit. It is 50 kilometres from the Murray River. Mount Barker was traditionally a farming area. Many of the lots just outside the town area are farming lots, although some of them have been replaced with new subdivisions in recent times.
