The municipality was unilingually Finnish. The name Eno comes from the Karelian word, which means the center of the river, where the water flows most strongly.[1] The beaver of the coat of arms on the triple hill refers to Majoinvaara in Eno, and the ax carried on its shoulder symbolizes deforestation and forestry. The coat of arms was designed by Ahti Hammar and approved by Eno's municipal council at its meeting on November 22, 1954. The coat of arms was approved for use by the Ministry of the Interior on April 15, 1955.[2]
Eno was consolidated with Joensuu on January 1, 2009.[3]
