Mount Buller is a resort town situated on the slopes of Mount Buller within the unincorporated area of the Australian state of Victoria. It lies approximately 208 kilometres northeast of Melbourne in the Victorian Alps, serving as a key alpine destination for the region. The settlement functions primarily as a ski resort and summer recreation hub, distinct from surrounding incorporated municipalities due to its special administrative status.

The area between Mount Buller and Mount Stirling serves as the primary catchment for the Delatite River, shaping the local geography. La Trobe University previously established a minor campus on the mountain, which included public cinema, gym, and indoor sporting facilities. Although the university has vacated the site, the Resort Management Board now utilizes the building, known as the Mount Buller Community Centre, as its headquarters.

The village features extensive accommodation facilities, offering around 7000 beds, the most of any Victorian ski resort. It is home to the National Alpine Museum and a growing network of first-class cross-country and downhill mountain bike tracks developed by WORLD TRAIL between 2009 and 2012. The mountain biking trails have been designated as a bronze-level IMBA Ride Center, with retail outlets providing hire and service for casual riders.

Mount Buller attracts snowsports enthusiasts in winter due to its proximity to Melbourne, while warmer months draw visitors for hiking and road cycling. The challenging climb from the tollbooth in Mirimbah to the village is a popular route for cyclists, featuring an average gradient of 6.2 percent. The resort also hosts the Victorian Downhill State Series and the MTBA National Series annually, cementing its reputation as a significant sporting venue.

At the 2016 census, Mount Buller had a population of 243, though it accommodates thousands of visitors during peak seasons. Access is via the single paved Mount Buller Road from Mansfield, requiring diamond-pattern wheel chains for all vehicles. The climate is very cold oceanic with cool summers and snowy winters, averaging 67.6 snowy days annually, making it one of the coldest mainland Australian sites.
