Broke is a rural locality of the Shire of Manjimup in the South West region of Western Australia, stretching along the coastline of the Southern Ocean. The South Western Highway forms the north-eastern border of the locality. Most of the locality as covered by national park, predominantly the D'Entrecasteaux National Park, except for the far east, which is covered by the Walpole-Nornalup National Park. The large Broke Inlet lies in the centre of Broke while, in the east, the locality lies on the shore of the Nornalup Inlet.

The origins of the name of the inlet and locality are debated, being linked to Brockman, Broke or Brooks. The inlet and locality's names are thought to be based on Philip Broke, captain of HMS Shannon, a frigate of the Royal Navy, best known for its victory over USS Chesapeake in 1813. Shannon is the name of both a river and a neighbouring locality. Both names were first recorded on a map in 1833.

The Shire of Manjimup is located on the traditional land of the Bibulman and Mineng people of the Noongar nation. The Mineng's traditional lands are in the far east of the shire, where the locality of Broke is also located, while the Bibulman's traditional lands are in the remainder of the shire.

The heritage listed Broke Inlet Houses, or Judy's Hut, a small rustic cottage, and Mottram Hut, a former drover’s hut, are located in Broke.
