The singers will reunite for "Brothers of the Sun" tour, which will take them to 19 stadiums from Florida to California.
"Tim and I have been great friends since we first toured together, and I can't wait to get back on the road with him," Chesney said in a statement. "He's one of my closest friends in music and in life, and I know this tour is going to be something special."
It's been 10 years since Chesney and McGraw were on the road together. The tour kicks off on June 2. There will be one show in California at the Angels Stadium in Anaheim on July 14.
"Our friendship was forged on the road, so it's going to be a blast heading out with Kenny again," McGraw said in a statement. "We'll be having as much fun on stage as the fans will be having in the audience."
