Gerardo Enrique Parra (born May 6, 1987 in Santa Barbara del Zulia, Venezuela) is a Major League Baseball left fielder for the Arizona Diamondbacks.
On May 13, 2009 he was called up from AA (Double A) Mobile BayBears when left fielder Conor Jackson was placed on the disabled list. He was inserted into the starting lineup the same day, and in his first Major League at bat he became the 100th player in MLB history to hit a home run in his first at bat. In his first five games he had at least one RBI, becoming the second player since Mike Lansing (1993) in the last 30 years to accomplish this feat. Parra was named NL Rookie of the Month for May and reached base in each of his first 17 games .
