Charlie Joiner Jr is a former professional football player. At Grambling University, Joiner played with quarterback James Harris and was a three-time All-Southwestern Athletic Conference selection.

Joiner graduated from Grambling in 1969 and was drafted in the fourth round by the American Football League's Houston Oilers. Joiner was a wide receiver in the American Football League (AFL) and NFL for 18 seasons. He is best known for his career with the San Diego Chargers (now the Los Angeles Chargers), with whom he spent 11 seasons. Before joining the Chargers, he played for the Houston Oilers and Cincinnati Bengals each for four seasons. It was with the Chargers' high flying "Air Coryell" offense under coach Don Coryell that Joiner had his most productive years, exceeding 1,000 yards receiving in a season four times and going to three Pro Bowls. Joiner was selected All-Pro in 1980 and 2nd Team All-AFC in 1976. Although he never played in a Super Bowl, Joiner helped the Chargers reach the AFC title game in the 1980 and 1981 seasons.

He retired with the most career receptions, receiving yards, and games played of any wide receiver in NFL history. Joiner was inducted into the Pro Football Hall of Fame in 1996. Joiner returned to San Diego as receivers coach from 2008 to 2012 before retiring after 44 years as a player and coach in football.
