The club has also extended contracts with batter Nick Larkin and bowler Jackson Coleman through the end of the BBL|11 season.
24-year old Hatcher is currently part of the NSW Blues state squad and has previously been part of the squad at Sydney Thunder.
Hatcher said he was pleased to join up with the Stars this season.
“I’m pretty excited to be joining the Melbourne Stars ahead of the upcoming season,” Hatcher said.
“I’d heard lots of good things about the club and the environment through Nick Larkin and I’m looking forward to meeting up with the players and coaches ahead of our first match in Canberra.”
