Porcupine Gorge National Park, National park in Queensland, Australia.

Porcupine Gorge National Park is a national park in northwestern Queensland featuring deep gorges carved through colorful sandstone cliffs. The rock formations display distinct layers and patterns created by ancient river activity over millions of years.

Porcupine Gorge National Park was established in 1970, covering 54.10 km2 in the Shire of Flinders, about 60 km north of Hughenden. It is managed by the Queensland Parks and Wildlife Service as an IUCN category II park. The gorge cuts through sedimentary strata spanning hundreds of millions of years, including Permian coal seams of the Betts Creek Beds, part of the Galilee Basin.

The creek's name comes from the Porcupine Creek that carved the gorge, and the park lies in Porcupine, Shire of Flinders. Visitors can look for the rock-wallaby, Pacific black duck, crimson-winged parrot and black bittern that use the gorge as habitat. The park is managed by the Queensland Parks and Wildlife Service.

The park has minimal facilities, so visitors should bring water, food, and camping equipment if staying overnight. The nearest shops and services are found in surrounding towns, so plan your supplies accordingly.

The Pyramid, a lone monolith of multi-coloured sandstone layers, stands in the wider part of the canyon. It survived because a thin basalt cap formed over the sandstone from a lava flow five million years ago, shielding the soft rock beneath from erosion.
