James Francis McNulty Jr. (October 18, 1925 – June 30, 2009) was a one-term congressman and U.S. politician hailing from the Democratic party.

He was born in Boston, Massachusetts and attended college at the University of Arizona where he was a member of Phi Delta Theta fraternity.

He defeated State Senator Jim Kolbe by around 1600 votes when the 5th District was created.

However, two years later, Kolbe unseated McNulty in a rematch, largely due to the district running about 60 percent for President Ronald Reagan.

McNulty resided in Tucson, Arizona with his wife Jacqui until his death on June 30, 2009.
