Vladimir Núñez Zarabaza (born March 15, 1975) is a Cuban former Major League Baseball relief pitcher.

He played for the Arizona Diamondbacks, Florida Marlins, Colorado Rockies, and Atlanta Braves.

On July 7, 2008, the Atlanta Braves purchased Núñez's contract from Triple-A Richmond after pitchers Manny Acosta and Jeff Bennett were placed on the disabled list.

He made his Braves debut and first major league appearance since 2004 that night against the Los Angeles Dodgers, tossing a scoreless eighth inning with one strikeout.

Núñez retired following the 2010 season and accepted the role of pitching coach for the Gulf Coast League Braves.
