Knights Hill is a geographical feature that is part of the Illawarra Escarpment. It is located south of Albion Park. The feature comprises a 709 metre above sea level summit, and several other small hills, atop a plateau adjacent to the escarpment edge. Atop the plateau are tv antennae and a small farm. The name first appears in a map by Surveyor Hoddle, after whom a track west of Kiama is named. He surveyed the region in the 19th century.
The hill can be seen from the coastal plain to the north as far as Stanwell Park. One of the television aerials emits a constant light pulse which can be seen from as far as Wollongong. The hill is one of the highest points of the escarpment, the highest being the 768 metre high Mount Murray, to the northwest.
