Stanton, appearing on ESPN's Baseball Tonight, said participating in the derby in his home stadium is "going to be so much fun, I'm really looking forward to it."
The Marlins will host the midsummer classic for the first time in franchise history.
Stanton had something of a home field advantage last year, as the Southern California native hit a total of 61 shots over the three rounds of last year's derby, which was held at San Diego's Petco Park.
With the hometown Miami fans on his side, Stanton will look to improve upon his 2016 performance in which he hit the 10 longest blasts of the exhibition.
The Home Run Derby will be held on July 10 and televised on ESPN.
