Saint-Maxime-du-Mont-Louis (French pronunciation: [sɛ̃ maksim dy mɔ̃ lwi]) is a municipality in Quebec, Canada.

[1] By 1863, Mont-Louis had grown to 200 inhabitants, and four years later, the Parish of Saint-Maxime-du-Mont-Louis was founded, which was named after Maxime Tardif (1821–1850), a secretary to Bishop Pierre-Flavien Turgeon.

[7] The locality has a humid continental climate (Dfb) in spite of its marine position with quite cold and snowy winters combined with warm but relatively short summers.

Due to its seasonal lag, September is quite some way above the 10 °C (50 °F) threshold for continental above subarctic, but the fifth-warmest month May is some way cooler than that.

However, the lag is not as intense as in other eastern Canadian localities, with July being significantly warmer than August.
