Gordon Keith Brown (August 31, 1960 – May 2, 2018) was a Canadian politician who represented the Ontario riding of Leeds—Grenville—Thousand Islands and Rideau Lakes in the House of Commons of Canada as a member of the Conservative Party from 2004 until his death.

Prior to entering federal politics, Brown was a Gananoque town councillor; President of the 1000 Islands-Gananoque Chamber of Commerce, and chair of the St. Lawrence Parks Commission (operators of Fort Henry, Upper Canada Village and other attractions).

Brown was appointed by Prime Minister Justin Trudeau, on the advice of Conservative Party of Canada Leader Andrew Scheer, to sit on the National Security and Intelligence Committee of Parliamentarians on November 6, 2017, and served on the committee until his death.

He also sat on several all-party caucuses focusing on rural, health, border and other issues and also participated in numerous parliamentary groups.

Brown was chosen in an earlier Parliament by then-Prime Minister Stephen Harper to chair the special committee that reviewed the Anti-Terrorism Act.
