Knights Hill is a hill that is part of the Illawarra Range with an elevation of 709 metres (2,326 ft) AMSL. The peak is located south of Albion Park and comprises several other small hills, atop a plateau adjacent to the escarpment edge.
Atop the plateau are TV antennas 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 Mount Murray at 768 metres (2,520 ft), to the northwest.
