James Kerrigan (December 25, 1828 – November 1, 1899) was an American military veteran who served one term as a United States representative from New York from 1861 to 1863.
After the war, he accompanied the Walker filibustering expedition to Nicaragua as a captain and served for a brief period as alcalde of the Nicaraguan capital.
Upon the outbreak of the American Civil War, he organized and then was commissioned Colonel of the 25th New York Volunteer Infantry Regiment, in the Union Army and served from May 19, 1861, until February 21, 1862.
Kerrigan was accused of harboring Confederate sympathies, and of not maintaining good order and discipline among his troops, and was allowed to resign his command.
While serving in the House, Kerrigan was arrested and removed from the floor for continuing to speak after his allotted time had expired in opposition to a bill funding the abolition of slavery in Missouri.
