Xavier Clifford Nady VI (pronounced /ɛkˈseɪvi.ər ˈneɪdi/; born November 14, 1978, in Salinas, California) is a Major League Baseball outfielder for the New York Yankees.

The St. Louis Cardinals originally drafted Nady in the 4th round of the 1997 Major League Baseball Draft (134th overall) after he was named Northern California Player of the Year in his senior year of high school, but he did not sign professionally at that time. After attending UC Berkeley, where he set the all-time Pac-10 Conference record for career slugging percentage (.729), Nady was drafted in the 2nd round of the 2000 Major League Baseball Draft by the San Diego Padres (49th overall). Nady signed a major league contract and became the 18th player to go directly to the major leagues without making his professional debut in the minor leagues since 1965.

Nady only appeared in one game and spent extensive time in the minor leagues following his debut. He was named Padres Minor League Player of the Year in 2001, also collecting the California League's Most Valuable Player and Rookie of the Year awards that season. Nady underwent Tommy John surgery and had limited playing time in 2002. In 2003, he again returned to the major league level for part of the season, but spent most of his time in the minor leagues.
