The Severn River, a perennial river that forms part of the Border Rivers group, is part of the Macintyre catchment of the Murray-Darling basin, located in the Darling Downs region of Queensland, Australia.

The Queensland branch of the Severn River rises on the western slopes of the Great Dividing Range south of Stanthorpe.

The river flows generally south by west, through the Sundown National Park, and forms its confluence with the Dumaresq River near the Tenterfield Creek and Glenlyon Dam Road, east of the settlement of Riverside.

The point where the rivers form their confluence marks part of the border between Queensland and New South Wales.

[citation needed] The Severn River descends 409 metres (1,342 ft) over its 90-kilometre (56 mi) course.
