Ménil-Hermei (French pronunciation: [menil ɛʁmɛ] ⓘ) is a commune in the Orne department in the Normandy region of north-western France.

The commune of Ménil-Hermei is part of the area known as Suisse Normande.

The Commune with another 20 communes shares part of a 2,115 hectare, Natura 2000 conservation area, called the Vallée de l'Orne et ses affluents.

[4] The commue has two rivers flowing through it, the Orne and its tributary the Baize.

It was by this route that the imposing stone pedestal of the monument to William the Conqueror, erected at the foot of Falaise Castle in 1850, was sent, causing considerable difficulties for the horse teams between "Forest Bridge" and Ménil-Hermei.
