Lucius Seth Huntington, PC (May 26, 1827–May 19, 1886) was a Canadian lawyer, journalist and political figure.

He also established a newspaper in Knowlton, later moving it to Waterloo after he was hired as secretary for a railroad company based there.

In 1873, he exposed the Pacific Scandal which led to the fall of Sir John A. Macdonald's Conservatives.

In 1875, Huntington was heavily criticized for a speech where he advised English Protestants in Quebec to vote Liberal to protect their own interests versus those of French Catholics.

He fell ill later in his parliamentary career and, after his defeat in 1882, moved to New York City to seek medical treatment.
