Hong Myung-Bo (Korean: 홍명보, Hanja: 洪明甫) (born February 12, 1969 in Seoul) is a former South Korean footballer who, along with Cha Bum Kun, is often considered among the greatest Asian footballers ever. Hong was a member of the Korean national team in four World Cups, and was the first Asian player to play in four consecutive World Cup finals tournaments. He played as either a centre-back or at full-back. He retired from playing following the end of the 2004 Major League Soccer season, having finished his career with the Los Angeles Galaxy. He was chosen among the "FIFA 100", Pelé's selection of the 125 greatest living footballers in the world. He was also the recipient of the 2002 FIFA World Cup Bronze Ball. No other Asian player has yet achieved this feat.

He managed the South Korea national under-20 football team in 2009, and led the team to the quarterfinals in the 2009 FIFA U-20 World Cup. Since being appointed in 2009, he has worked as head coach of the under-23 football team.

Hong's first appearance at a World Cup final was at the 1990 World Cup in Italy. Hong played in all of Korea's matches against Belgium, Spain, and Uruguay, all three of which Korea lost.
