Louis Archambeault (French pronunciation: [lwi aʁkɑ̃bo]; November 7, 1814 – March 3, 1890) was a Quebec notary and political figure.

In the same year, he was accused of having inflated his expenses while serving as a returning officer in two earlier elections.

In 1867, he was commissioner of agriculture and public works in the provincial cabinet and he also represented Repentigny in the province's Legislative Council.

He was accused of involvement in the Tanneries scandal of 1874 which led to the fall of the provincial government of the time.

Archambeault also helped introduce a provincial board to oversee Quebec notaries.
