Mount Colosseum National Park, National park in Central Queensland, Australia

Mount Colosseum National Park protects Mount Colosseum, an old volcanic dome and the dominant feature on the skyline of the area, which rises to 470 metres. The summit is sparsely covered with hoop pines, while subtropical rainforest with ironbark and bloodwood eucalypts grows on the lower slopes. The park lies west of the Bruce Highway, about 6 kilometres south of Miriam Vale.

Mount Colosseum is an old lava dome, and the national park protects its summit and lower slopes. The sources consulted give no founding date or later boundary changes, so the 1977 and 1994 dates in earlier descriptions are unsupported. The park lies west of the Bruce Highway, near the Bundaberg–Gladstone railway by the settlement of Makovata.

The name comes from the mountain's resemblance to the Colosseum in Rome, a comparison made by early European settlers. The park lies west of the Bruce Highway near the settlement of Makovata, on the Bundaberg–Gladstone railway line. The mountain is a local landmark visible from the road between Miriam Vale and Seventeen Seventy.

The park sits around 370 kilometers northwest of Brisbane and can be reached without much difficulty from the outside. Since there are no marked trails or developed facilities, a visit requires preparation and is best planned during the drier months.

The park lies west of the Bruce Highway beside the Bundaberg–Gladstone railway line, near the settlement of Makovata. From Miriam Vale, visitors turn southeast towards Seventeen Seventy, follow that road for 6 km, then turn southwest for another 5 km to the park entrance.
