Franco Harris (born March 7, 1950) is a former American football player best known for his career with the Pittsburgh Steelers.

In the 1972 NFL draft he was chosen by the Pittsburgh Steelers in the first round, the 13th selection overall. His selection by the team was considered controversial at the time, as many thought the team would select his Penn State teammate, Lydell Mitchell. (Mitchell was later selected by the Baltimore Colts in the draft.) He played his first 12 years in the NFL with the Steelers; his 13th and final year (1984) was spent with the Seattle Seahawks. He was inducted into the Pro Football Hall of Fame in 1990.

Harris was born in Fort Dix, New Jersey. His father was an African-American man who served in World War II; his mother was a "war bride" from Italy. Harris went to Rancocas Valley Regional High School in Mount Holly Township, New Jersey, and then attended Penn State University. While playing for the Penn State Nittany Lions, Harris served primarily as a blocker for the Nittany Lions' All-American running back Lydell Mitchell.
