George Waters Allsopp (1769 – September 28, 1837) was a seigneur, businessman and political figure in Lower Canada.
He was born in 1769, probably at Quebec City, the son of George Allsopp, and studied at Eton College near London.
He purchased his father's grist mills and part of the seigneury in 1795.
Allsopp was elected to the Legislative Assembly of Lower Canada for Buckinghamshire in 1796.
In the late 1820s, with his brothers, he erected a toll bridge across the Jacques-Cartier River.
