Saint-Adelme (French pronunciation: [sɛ̃t‿adɛlm]) is a parish municipality in the Canadian province of Quebec, located in La Matanie Regional County Municipality in the Bas-Saint-Laurent region.

In 1864, the area was surveyed and the geographic township of Saint-Denis was created.

The Mission of Saint-Denis was founded in 1916, but real growth came in the 1920s, during the period of colonization of the Chic-Chocs plateau.

For unknown reasons, the place, that was originally known as Saint-Denis, came to be called Saint-Adelme.

On September 9 that same year, the Parish Municipality of Saint-Adelme was formed out of territory ceded by the Parish Municipalities of Saint-Jérôme-de-Matane and Sainte-Félicité, as well as some previously unorganized territory.
