was an English professional footballer and manager who played as a centre-back for Leeds. He was part of the England national team that won the 1966 World Cup and managed the Republic of Ireland national team from 1986 to 1996, taking them to two World Cups and one European Championship. He was the elder brother of Manchester United forward Bobby Charlton and one of his teammates in England's World Cup final victory.

His 629 league and 762 total competitive appearances are club records. In 2006, Leeds United supporters voted Charlton into the club's greatest XI.

Called up to the England team days before his 30th birthday, Charlton went on to score six goals in 35 international games and to appear in two World Cups and one European Championship. He played in the World Cup final victory over West Germany in 1966 and helped England finish third in Euro 1968 and win four British Home Championship tournaments. He was named FWA Footballer of the Year in 1967.

After retiring as a player, Charlton worked as a manager. He led Middlesbrough to the Second Division title in 1973–74, winning the Manager of the Year award in his first season as a manager.

He left the Owls in May 1983 and served Middlesbrough as caretaker-manager at the end of the 1983–84 season. He worked as Newcastle United manager for the 1984–85 season. He took charge of the Republic of Ireland national team in February 1986 and led them to their first World Cup in 1990, where they reached the quarter-finals.
