Manaslu Conservation Area is a protected area in Nepal. Established in 1998 it covers 1,663 km² in the Mansiri Himal range of the Himalayas in the Gorkha District. The area comprises mountains, glaciers, and watercourses. In elevation, the area ranges from 1,400 to 8,156 m at the peak of Manaslu.

There are about 9,000 inhabitants living in MCA and over 2,000 species of plants, 39 mammals, 201 birds, 3 reptiles and 11 butterflies in 11 types of forest have been reported from the area. With the declaration of MCA in 1998, Government of Nepal handed over the management responsibility of MCA to NTNC for 10 years. The objective was to improve the capacity of the local communities in the Manaslu area to benefit from tourism in an environmentally benign manner for sustainable development. With the expiry of the management mandate, on the request of the local communities, the District Development Committee of Gorkha and the major political parties in the district, the Government of Nepal has extended the management mandate for another 10 years.
