The Walls of Jerusalem National Park is a national park located in the Central Highlands region of Tasmania, Australia. The park is located approximately 144 km (89 mi) northwest of Hobart, east of the Cradle Mountain-Lake St Clair National Park, and west of the Central Plateau Conservation Area. It is south of Mole Creek, Tasmania, and Rowallan Lake. The national park forms part of the Tasmanian Wilderness World Heritage Area.

The locality of Walls of Jerusalem is in the local government areas of Central Highlands (36%) and Meander Valley (64%) in Tasmania. The locality is about 244 kilometres (152 mi) north-west of the town of Hamilton.

The park takes its name from the geological features of the park which are thought to resemble the walls of the city of Jerusalem. As a result, many places and features within the park also have Biblical references for names, such as Herods Gate, Lake Salome, Solomons Jewels, Damascus Gate, the Pool of Bethesda.

The most prominent feature of the park is King Davids Peak with an elevation of 1,509 metres (4,951 ft) above sea level.

Much of the walking track consists of raised boards, from Wild Dog Creek through to Dixon's Kingdom, with the purpose of protecting the fragile alpine vegetation. Walking tracks elsewhere in the park consist of rock, rocky earth, grassland and marsh.

Some scenes for the second episode of the BBC documentary series Walking with Dinosaurs were filmed here.

The locality has an area of 517.7 square kilometres (199.9 sq mi), all of which is occupied by the national park.

The C171 route (Mersey Forest Road) runs south just outside the north-western boundary (in the locality of Mersey Forest) to the Walls of Jerusalem car park, where it ends.
