The Grampians is a mountain range and national park in Victoria (Australia), 235 km west of Melbourne. The Grampians feature a striking series of sandstone mountain ranges. The ranges were named in 1836 by NSW Surveyor-General Sir Thomas Mitchell after the Grampian Mountains in his native Scotland, but are also known by the Aboriginal word Gariwerd.

The general form that the ranges take is, from the east, a series of low-angled sandstone ridges running roughly north-south. The western sides of the ridges, where the sedimentary layers have faulted, are steep and spectacular, beyond the vertical in places - notably at Hollow Mountain near Dadswell's Bridge at the northern end of the ranges. The most popular walking area for day trippers is the Wonderland area near Halls Gap. In summer the ranges can get very hot and dry. Winter and spring are the best times for walking. In spring the Grampians wildflowers are a major attraction. The area is a noted rock climbing destination, and it is popular with campers and bushwalkers for its many spectacular views and unspoilt nature.

Halls Gap is the largest service town in the area and is located at a point roughly equidistant between the towns of Ararat and Stawell. The town is located towards the eastern (Melbourne) side of the park and offers accommodation to the many tourists who visit the area.
