Falher (/fəˈlɛər/; fə-LAIR, French pronunciation: [fɑlɛːʁ])[6] is a town in the Peace Country area of Alberta, Canada.

Falher is notable for its sizable francophone population, having the highest percentage of French speakers of any municipality in Western Canada, with 52% able to speak the language as of 2021.

[8] The surname is ultimately derived from Breton falc’her (cognate with French faucher) meaning “scytheman.” When the mission was officially elevated to a parish by Bishop Émile Grouard on June 14, 1917, he chose to erect it under the patronage of Saint Anne as there was already a mission named Saint-Jean-Baptiste in present-day Fort McMurray, built a year prior to that in Falher.

The settlements of Falher, Donnelly and Girouxville were referred to by the Cree jointly as umstosee owuskee, meaning “Frenchman’s Land.”[9] J. Fromhold provides the alternate Cree name of mistik asissw owaski to Falher and Donnelley, literally “Little Stick House" (in reference to the mission church), the Cree supposedly identifying the French as the mistik asis iniw or “Little Stick People.”[10] The area was known to missionaries before it was surveyed in 1909 as an Indian trail that led to British Columbia and where the Edmonton, Dunvegan and British Columbia Railway later laid its tracks.

The origin of the majority of local colonizers were from Quebec; some arriving in the area via the United States of America (French American), such as Robert Goulet's family, who settled in Girouxville.

Under normal circumstances, Falher Alfalfa employed a staff of about 35 full-time employees in the spring and 110 at the busiest time of the season.

Beginning in 1970, each June, the Falher Honey Festival is held to pay tribute to the beekeeping industry which has created an impact in the Smoky River region and throughout Canada and the United States.

The arena is home to the Falher Pirates, a team within the East Division of the North Peace Hockey League.
