Arthur Anthony DeCarlo, Jr. (March 23, 1931 – December 28, 2013) was an American professional football defensive back and end in the National Football League (NFL). He played a total of six seasons for the Pittsburgh Steelers, Washington Redskins, and Baltimore Colts.

A former collegian at the University of Georgia, DeCarlo was originally drafted in the sixth round of the 1953 NFL draft by the Chicago Bears.

DeCarlo would win two World Championships in 1958 and 1959 as a member of the Colts. He retired after the 1960 season.

Following his death from complications of heart surgery in 2013, DeCarlo's family made his brain available as part of a pioneering study of the prevalence of chronic traumatic encephalopathy (CTE) in former professional football players. DeCarlo's brain was found to be positive for the degenerative disease.

Art DeCarlo was born March 23, 1931, in Youngstown, Ohio. His father, Antonio DeCarlo, was a contractor.

His parents died when he was still a minor and he was raised by an older brother, working in a steel mill the summer after he graduated from high school.

An athlete from his high school years, DeCarlo had offers to attend various colleges to play football. A classmate encouraged him to travel to Athens, Georgia, to try out for the Bulldogs, however, and helped buy a one-way ticket.

Always a versatile athlete, DeCarlo played five different positions for the Bulldogs, including end and halfback.
