As coach Iván Alvarez DeJesús (born January 9, 1953) is a Puerto Rican former professional baseball shortstop and coach, who played in Major League Baseball (MLB) for the Los Angeles Dodgers, Chicago Cubs, Philadelphia Phillies, St. Louis Cardinals, New York Yankees, San Francisco Giants, and Detroit Tigers, for 15 seasons (1974–1988).

In 1981 he finished with a .194 batting average, zero home runs, and 13 RBIs garnering the unofficial anti-triple crown for having the lowest number among qualified batters in average, RBI and home runs.

Since 2001 DeJesús has been a manager with various Astros minor league teams, and received the 2003 Player Development Man of the Year award.

Previously he worked as a special assistant to Cubs manager Lou Piniella.

DeJesús is mentioned in the Mojo Nixon and Skid Roper song "Where the Hell's My Money", in which Skid takes out his washboard, "winds up like Iván DeJesús" and hits a thieving club owner in the face with it.
