Adrián Beltré Pérez (born April 7, 1979 in Santo Domingo, Dominican Republic) is a Major League Baseball third baseman who plays for the Seattle Mariners. Previously, he played for the Los Angeles Dodgers (1998-2004). He bats and throws right-handed.

He was signed out of the Dominican Republic by the Los Angeles Dodgers in 1994. Beltré attended Liceo Maximo Gomez High School, where he developed into one of the school’s top players. In 1994, while working out at Campo Las Palmas, the Los Angeles Dodgers facility, he was spotted by scouts Ralph Avila and Pablo Peguero. Though only 15 and weighing just 130 pounds, he had a lightning-quick swing and electric throwing arm. On the insistence of Avila and Peguero, the Dodgers signed Adrian in July. He received a $23,000 bonus. When it was revealed that Beltre had signed his initial contract at the age of 15, commissioner Bud Selig suspended the Dodgers' scouting operations in the Dominican Republic for a year, due to the fact that signing a player at that age was prevented under MLB rules.

Beltré debuted with the Dodgers in the 1998 season at age 19.
