Enrique Romo Navarro (born July 15, 1947 in Santa Rosalía, Baja California Sur, Mexico) is a former relief pitcher in Major League Baseball who played for the Seattle Mariners (1977–78) and Pittsburgh Pirates (1979–82). Romo batted and threw right-handed. He is the younger brother of Vicente Romo, who also pitched in the majors.

In a six-season career, Romo posted a 44–33 record with a 3.45 ERA, 52 saves, and 436 strikeouts in 350 games pitched.

Romo pitched 11 seasons in Mexican baseball prior to making his major league debut for the Seattle Mariners in 1977 at the age of 29. In his rookie season, he led the Mariners with 16 saves. He was traded to the Pittsburgh Pirates after the 1978 season in a multi-player deal which brought, among others, the infamous Mario Mendoza to the Mariners.

His most productive season came in 1979 for World Series Champion Pittsburgh, with whom he had a 10–5 mark, a 2.99 ERA, career-highs in games (84) and innings (129.3), exclusively as a set-up man for closer Kent Tekulve. Romo also made two appearances in the World Series, won by Pittsburgh over the Baltimore Orioles in seven games. In 1980, he slugged a grand slam home run.

In 1983, Romo failed to report to spring training, first indicating he would arrive late due to one of his children dealing with chicken pox, and then later not attending at all, announcing the intention to join an unsanctioned league in Mexico. Pittsburgh warned Romo that such a move would require them to fine him $500 for each day of camp that he missed; ultimately, Romo remained in Mexico.
