L'Ascension-de-Patapédia (French pronunciation: [lasɑ̃sjɔ̃ də patapedja]) is a municipality in Quebec, Canada.

Being surrounded by large tracts of boreal forest, the place is economically dependent on the forestry industry, as well as some hunting and fishing tourism.

[4] While the geographic township of Patapédia was proclaimed in 1881, it was not until 1937 that the village was founded.

That same year the Parish of L'Ascension-de-Notre-Seigneur (French for "Ascension of Our Lord") was established.

In 1968, the Municipality of L'Ascension-de-Patapédia was incorporated, named after the parish and the township.
