Endy de Jesus Chávez Meza (/ˈtʃɑːvɛz/; born February 7, 1978), is a Venezuelan former professional baseball outfielder. He played in Major League Baseball (MLB) for the Kansas City Royals, Montreal Expos / Washington Nationals, Philadelphia Phillies, New York Mets, Seattle Mariners, Texas Rangers, and Baltimore Orioles. Chávez is the older brother of Ender Chávez.

Chávez was born in Valencia, Venezuela where his father, Alirio, worked as a handyman. Growing up in Venezuela, he honed his hand-eye coordination by hitting pebbles out of the air with sticks. He initially drew attention from Colorado Rockies scouts at 18 years old but, when their interest wavered due to his slight stature, he signed with the New York Mets.

Chávez made his Minor League Baseball debut in 1997 with the Gulf Coast League Mets, a rookie-level affiliate of the New York Mets. He remained in the Mets organization through 2000, spending time with the Kingsport Mets, Gulf Coast Mets, Capital City Bombers, and St. Lucie Mets. On December 11, 2000, Chávez was claimed by the Kansas City Royals in the 2000 Rule 5 draft. On March 30, 2001, Chávez was returned to the Mets and then traded to the Royals for minor league outfielder Michael Curry. He played for the AA Wichita Wranglers and the AAA Omaha Royals before making his major league debut with the Royals on May 29, 2001.

In the winter of 2001, Chávez was waived by the Royals and then claimed and waived by both the Mets and Detroit Tigers before being claimed by the Montreal Expos where he played in 309 games over three years (2002–05) while splitting time at AAA Ottawa and Edmonton. Playing full-time for the Expos in 2003 and 2004, Chávez batted first in the lineup and started in center field, stealing 18 bases in 2003 and 32 in 2004. On October 3, 2004, Chávez recorded the final out in Expos history in their 8–1 loss to the Mets at Shea Stadium. In 2005 Chávez played in only seven games in the majors for the now-relocated Washington Nationals before being traded to the Philadelphia Phillies for fellow outfielder Marlon Byrd. During his tenure in Washington, Chávez was given the mocking nickname of "Inning Endy" by Nationals fansites due to his tendency to swing away rather than work the count to his favor which often resulted in groundouts and popups to end the Nationals innings.

Chávez spent the rest of the 2005 season with the Philadelphia Phillies and appeared in 91 games with 107 at-bats and hit only .215. At the end of the season, Chávez became a free agent for the first time and signed one year, $500,000 contract with the Mets on December 23, 2005.

During spring training, Mets manager Willie Randolph worked with Chávez to improve his hitting. Chávez's speed and his modified batting style sparked a 90-point jump in his batting average over the previous season (hitting .306 in 353 at-bats) as the Mets' fourth outfielder (often as an injury replacement for regular left fielder Cliff Floyd). His improved hitting and excellent defensive skills contributed to the Mets winning the National League East.

Chávez's signature moment came at Shea Stadium in Game 7 of the 2006 National League Championship Series. In the top of the sixth inning, with the game tied, 1–1, Cardinals third baseman Scott Rolen hit a pitch off Mets starter Óliver Pérez. Leaping over the 8-foot-high (2.4 m) left field wall, Chávez caught the ball with the tip of his glove to rob Rolen of a two-run home run. Chávez then threw to cutoff man second baseman José Valentín, who threw to Carlos Delgado at first base to double off Cardinals center fielder Jim Edmonds for an inning-ending double play. Although the Mets went on to lose the game and the series, "The Catch" was named the top post-season moment in the fifth annual This Year in Baseball Awards. On July 13, 2007, American International Group (the company whose left field advertisement was where Chávez made the catch) sponsored a special bobblehead doll day to commemorate the catch. The left field entrance gate of the Mets' current ballpark, Citi Field, features a metal silhouette of a baseball player making a leaping catch similar to the one Chávez made during the 2006 NLCS.

Chávez's playing time decreased dramatically in 2007 when he only saw time in 71 games, primarily splitting time with regular left fielder Moisés Alou, due to left hamstring issues which landed him on the disabled list twice. That winter, he reinjured his hamstring and injured his right ankle while playing winter ball in Venezuela for Navegantes del Magallanes.
