Engerdal is a municipality in Hedmark county, Norway. It is part of the traditional region of Østerdalen. The administrative centre of the municipality is the village of Engerdal. The new municipality of Engerdal was created on 1 January 1911 from parts of the municipalities of Tolga, Trysil, Ytre Rendal, and Øvre Rendal.

The first element is the river name Engera and the last element is dal, the word for "valley" or "dale". The river name is derived from the name of the lake Engeren, and this is probably derived from the Old Norse word ongr which means "narrow".

The coat-of-arms is from modern times. They were granted on 8 February 1991. The arms show two pieces of a horse harness (the hames) in gold on a green background. The two objects symbolize the ties between horse and man and at the same time the connection between work and recreation.

The municipality is located in the northeast part of Hedmark county. It is bordered by Sweden to the north and east, the municipality of Trysil to the south, Rendalen to the west, and Os and Tolga to the northwest.

The greater part of Lake Femunden and roughly half of the Femundsmarka National Park also lie within the boundaries of the municipality.

Engerdal consists of two national parks. Femundsmarka National Park was founded in 1971 and is situated in the north-east of the municipal. The area is popular for its many lakes and attracts a lot of sport - fishers every year. The same lakes are also perfect for padling the canoe. Due to its large continuously, untouced and protected area, the national park is one of Southern-Scandinavia largest and the area has become a base for many rare animal species.
