Sir James Stuart, 1st Baronet of Oxford (March 2, 1780 – July 14, 1853) was a lawyer, judge, and political figure in Lower Canada.
He was born in Fort Hunter, New York, in 1780, the son of the Anglican priest John Stuart, a United Empire Loyalist.
He studied at King's College in Windsor, Nova Scotia and then apprenticed in law in Lower Canada with John Reid and then Jonathan Sewell; he was called to the bar in 1801.
He was defeated in 1810, but elected for Montreal County in an 1811 by-election and served as leader of the Parti canadien, replacing Pierre-Stanislas Bédard.
His nephew George Okill Stuart later served in the legislative assembly for the Province of Canada and also as a mayor of Quebec City.
