Marcelo Andrés Ríos Mayorga (Latin American Spanish: [maɾˈselo ˈri.os]; born 26 December 1975) is a Chilean former professional tennis player. He was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP), the first Latin American to reach the top position. Ríos won 18 ATP Tour-level singles titles, including five Masters events, and was the runner-up at the 1998 Australian Open. He is the only man in the Open Era to have been world No. 1 without ever winning a major singles tournament.

Ríos was the first player to win all three clay court Masters tournaments (Monte Carlo, Rome, and Hamburg) since the format began in 1990. He was also the third man (after Michael Chang and Pete Sampras) to complete the Sunshine Double (winning Indian Wells and Miami Masters in the same year), which he achieved in 1998. At 1.75 m (5 ft 9 in), Ríos is the shortest man to hold the number 1 ranking. He also held the top ranking in juniors.

Ríos retired from the sport in July 2004, due to a long-term back injury. He played his last ATP Tour-level tournament while only 27 years old at the 2003 French Open.
