Luis Aguayo Muriel (born March 13, 1959 in Vega Baja, Puerto Rico) is a former player and coach in Major League Baseball.

Aguayo was originally signed by the Philadelphia Phillies as an amateur free agent on December 27, 1975 at the age of 16. He would debut for the Phillies on April 19, 1980, a win over the Expos. He entered the game in the top of 3rd inning as a pinch runner for Manny Trillo, and would play second base for the remainder of the game. Although Aguayo would play with the Phillies until 1988, he only appeared in two games in the 1981 postseason, acting as a pinch runner in the series against the Dodgers. According to some metrics, Aguayo ranked 76th in the National League according to statistics in 1985.

He would be traded to the New York Yankees in the middle of July, 1988 for minor leaguer Amalio Carreño, and would sign with the Cleveland Indians after the season. Aguayo only appeared in 47 games for the Indians before being released after the 1989 season, and would linger in the minor leagues until 1992, batting .255 in 80 games for the Pawtucket Red Sox.

On June 17, 2008, Aguayo was named the New York Mets third base coach. On October 23, 2008, the New York Mets announced Aguayo would be reassigned within the organization and that Razor Shines would be replacing him as third base coach. He is currently the international field coordinator/infield instructor for the minor league staff of the St. Louis Cardinals.
