Bellthorpe National Park, Nature reserve in Queensland, Australia

Bellthorpe National Park covers 75.5 km² of the southern Conondale Range, west of the Glass House Mountains, in the City of Moreton Bay and Somerset Region. Its terrain is rugged, rising to about 650 m and carrying open eucalypt forest and subtropical rainforest. Stony Creek, a tributary of the Stanley River, runs through the park with small waterfalls, cascades and a rock pool; parts were once known as Bellthor.

Bellthorpe National Park was gazetted on 26 March 2010, covering 75.5 square kilometres across Bellthorpe, Booroobin and Sandy Creek in the City of Moreton Bay and Somerset Region. Parts of the park had earlier been known as Bellthor. Its forests also hold remnants of a once prosperous timber-cutting industry, and the land now forms part of the southern Conondale Range conservation area alongside Conondale, D'Aguilar and Maleny national parks.

The park's name comes from the small town of Bellthorpe at its north-eastern end, and parts of the area were once known as Bellthor. Timber cutting was a prosperous industry here, and remnants of that period remain in the forest today. Visitors now come for horse riding, mountain biking and bushwalking on the unsealed forest roads.

The Stony Creek day-use area offers accessible facilities including toilets, picnic tables, and barbecues for visitors. These amenities make it easy to spend time exploring the forest without complicated planning.

The park has no marked walking trails, so the small waterfalls, cascades and rock pool along Stony Creek are reached by following unsealed forestry roads on foot, on horseback, by mountain bike or by four-wheel drive. Remnants of a former timber-cutting industry remain in the forest.
