"Today is exactly 30 YEARS since The @FreshPrince of Bel-Air debuted!" Smith wrote on his Instagram. "So we're doin' something for y'all … a for real Banks Family Reunion is comin' soon to @HBOmax!"
The actor also made mention to James Avery, who died at the age of 68 in 2014. He portrayed Uncle Phil.
"RIP James," he wrote. "#FreshPrince30th."
Not a lot is known about the special just yet, but it will air in the US on streaming service HBO Max, which generally indicates it will drop on Binge in Australia.
The series, which ran from 1990 to 1996 and developed a huge following, is also reported to also be in talks for a reboot.
There were reports late last year a potential reboot was to be managed by Westbrook Inc, a new media company co-founded by Will and his wife Jada Pinkett Smith, however there is no confirmation of that yet.
Smith has been known to reunite with his old cast mates, often sending fans wild on social media with pics from the gatherings.
During an appearance on The Graham Norton Show, he joked that he would have to play the Uncle Phil role these days, given that he's in his 50s.
Original Uncle Phil actor Avery passed away in 2014.
