Francis Joseph Kilroy (May 30, 1921 – July 10, 2007), nicknamed "Bucko", was an American football player, executive and administrator.

Kilroy was originally recruited by the Notre Dame Fighting Irish, but went on to become one of the finest linemen in Temple Owls football history.

He helped them to defeat rivals Penn State, Bucknell and Villanova in the 1941 season for the first and only time in school history.

A two-way line starter for championship teams in 1948 and 1949 and for runners-up in 1947, Bucko helped Steve Van Buren win several NFL rushing titles in that time span.

Hall of Famer defensive tackle Art Donovan had this to say about him: "The beginnings of the Colt-Eagle rivalry probably had something to do with a guy named Frank Kilroy.

As the head of scouting in early 2000s, Bucko was instrumental in drafting many of players that won three Super Bowls for the Patriots.

In 2022, the Professional Football Researchers Association named Kilroy to the PFRA Hall of Very Good Class of 2022.
