Joseph Albert "Jo-Jo" Reyes (born November 20, 1984 in West Covina, California) is a starting pitcher in Major League Baseball who plays for the Atlanta Braves organization. Listed at 6'2", 230 lb., Reyes bats and throws left-handed.

Reyes was drafted by the Braves out of Riverside Polytechnic High School in the second round (43rd overall) of the 2003 MLB Draft. He spent his entire first professional season in the Gulf Coast League. In 10 starts with the Gulf Coast Braves, Reyes went 5-3 with a 2.56 ERA and 55 strikeouts in 45.0 innings pitched. He allowed just one home run all season.

With Class-A Rome in 2004, Reyes struggled most of the season, going 2-5 with a 5.33 ERA. Tommy John surgery kept him out for the end of the year and the first half of the 2005 season. He was sent back to the GCL in 2005, and after doing well received a mid-season promotion to Class-A Danville. While his strikeout total fell (27 in 43 innings), he went 3-0 with a 3.53 ERA and posted a WHIP of 0.99, but a torn anterior cruciate ligament (ACL) ended his season prematurely.
