The Indian Forest Service (IFoS) is one of the top three civil services of the Union government, and officers recruited through the Union Public Service Commission (UPSC) work in the forest department, and are responsible for conservation of natural resources and maintaining ecological stability in the country. The officers are also mandated to implement the National Forest Policy (NFP).

In 1938, the Indian Forest College (IFC) was founded at Dehradun, and the officers recruited are trained there.

The IFoS cadre is allocated to the Ministry of Environment and Forests, and acts as a nodal ministry to implement rules and regulations. The officials in states and Union Territories take roles such as the Conservator of Forests, Chief Conservator of Forests, Additional Principal Chief Conservator of Forests, and Principal Chief Conservator of Forests.
