Luis Enrique Ugueto [oo-geh-to] (born February 15, 1979, in Caracas, Venezuela) is a former Major League Baseball second baseman and switch-hitter who played for the Seattle Mariners in 2002 and 2003.

Originally signed by the Florida Marlins as an amateur free agent in 1996, he was drafted by the Pittsburgh Pirates from Florida in the 2001 Rule 5 draft, and was traded to the Mariners for cash the same day. Finally, he made his debut with the Mariners on April 3, 2002.

Ugueto was a promising young infielder with a strong arm and blistering speed on the bases.^{[citation needed]} What Seattle hoped would develop was his bat and his overall feel for the game, especially defensively, at the major league level.^{[citation needed]} In two seasons as a backup with the Mariners, Ugueto batted .214 with one home run and two RBI in 74 games.

Ugueto signed with the Kansas City Royals prior to the 2005 season and spent the season with the Royals' top minor league club, the Omaha Royals. While with Omaha, he was suspended twice for violating baseball's steroid policy, and he was released by the Royals after the second violation.^{[citation needed]}

After missing the entire 2006 season, Ugueto played with the Minnesota Twins minor league team, the Fort Myers Miracle during the 2007 season. In 2008, he played in Italy's Serie A1 for the Caffè Danesi Nettuno and hit .289. He also shortly played for the Laredo Broncos.
