Tom Cross (born July 31, 1958) is an American lawyer and former Republican member of the Illinois House of Representatives where he served from 1993 to 2015.

He served as House Minority Leader from January 2002 to August 2013, when he resigned to run for Illinois Treasurer.

Burris had reportedly not mentioned fund-raising contacts allegedly made to him by Blagojevich's brother, Robert Blagojevich, in his testimony, but then filed an affidavit with Democratic impeachment committee chair Barbara Flynn Currie, listing three such contacts, shortly after February 5.

Word of the new information did not reach the public, or the Republicans in the House, until its release in the Chicago Sun-Times on February 13.

In April 2016, Cross's brother Scott came forward as being "Individual D" in the trial of former U.S. House Speaker Dennis Hastert.
