Pigeon House Mountain (Aboriginal: Didthul[1]) is a mountain at an elevation of 720 metres (2,360 ft) AHD[2] on the Budawang Range that is situated within the Morton National Park,[1] located on the South Coast region of New South Wales, Australia.

Pigeon House Mountain is a popular walking destination, taking an average of three to four hours for a complete ascent and descent from the car park.

Pigeon House Mountain is home to eastern grey kangaroos and superb lyrebirds.

The mountain was first seen by Captain James Cook at 7 a.m. on 21 April 1770, during his voyage of discovery along Australia's eastern coast.

Cook described - a remarkable peaked hill which resembled a square dovehouse with a dome on top and for that reason I called it Pigeon House.
