Junction Falls is the name for two waterfalls located within the South Lawson Waterfall Circuit, in Lawson, New South Wales. They are the second and third falls in the circuit, and is accessed from a 0.9 kilometres (0.56 mi) trail from the Northern Entrance/Carpark of the circuit. The two falls are named Junction due to them being at the junction of Ridge Creek and Lawson Creek.

Junction Falls are located in the South Lawson Waterfall Circuit, 0.9 kilometres (0.56 mi) from the northern carpark, and consists of two waterfalls at the junction of Ridge and Lawson Creek. Eastern Whipbirds and Musky rat-kangaroos are found in the track near Junction Falls, and many Blue Gums are also present.

The second fall of Junction Falls, Junction Falls II, is located shortly due east of the main falls, and has a small overhang directly below the falls. Ferns and other Australian Native Plants are above the falls. The watercourse of Junction Falls II ends just after the footbridge over Lawson Creek.

The bottom of the first Junction Falls has clay exposed, due to the erosion of the rock underneath. Near the base of the falls, there is a rock with a small plaque, dedicated to a hiker who passed away in Slovenia, Prue Angell. It read that the Five Waterfall Walk was her favourite walk. There is a small footbridge across Lawson Creek to the south of the falls.
