Lorrainville (French pronunciation: [lɔʁɛ̃vil]) is a municipality in northwestern Quebec, Canada, in the Témiscamingue Regional County Municipality.

The settlement was named after Narcisse-Zéphirin Lorrain (1842-1915), bishop of Pembroke at that time.

The place saw significant growth in 1905, when it became an important agricultural centre.

[1][5] In 1930, the village centre of the parish municipality separated to become the Village Municipality of Lorrainville, with Eddy Guimond as its first mayor.
