Mount Duval, a large forested mountain of the New England Range, part of the Great Dividing Range, is located on the Northern Tablelands in the New England region of New South Wales, Australia.

With an elevation of 1,393 metres (4,570 ft) above sea level,[1] Mount Duval is one of the largest peaks in the area, dominating the Armidale skyline located approximately 15 kilometres (9.3 mi) to the south of the summit.

Mount Duval features on the logo of the Armidale Dumaresq Council.

When viewed from Armidale, Little Mount Duval appears much smaller and was so named accordingly.

On the summit of Little Mount Duval sit the transmission relay towers for a number of radio and television stations that broadcast into Armidale.
