The winningest manager in team history will be celebrated on Aug. 9 before Philadelphia plays the Mets. Manuel will become the 36th member of the club.
Manuel led Philadelphia to five straight NL East titles and the franchise's second World Series crown in 2008. He was fired last August, and last month accepted a job as a senior adviser to general manager Ruben Amaro Jr.
"I am honored to be enshrined on the Wall of Fame with Phillies greats such as Mike Schmidt, Steve Carlton and, of course, my good friend, Dallas Green," Manuel said in a statement. "The years I spent in Philadelphia were some of the best of my professional career and I owe a lot of that to the fans. I have said this before, but they are the best in the game."
