George Okill Stuart QC (October 12, 1807 – March 5, 1884) was a Canadian lawyer, political figure, and judge.

He was born in (York, later Toronto), Upper Canada in 1807, the son of George Okill Stuart and was educated at Kingston and Quebec City.

He articled in law with his uncle, James Stuart, and was admitted to the Lower Canada Bar in 1830.

In 1873, he became an assistant to his wife’s uncle, Henry Black, a judge in the Vice Admiralty Court at Quebec.

When Black died later that year, Stuart was chosen as his replacement and served in that function until his death at Quebec City in 1884.
