2 Chainz is getting into the business side of basketball ... announcing he just bought a minority ownership stake in the Atlanta Hawks G League team, the College Park Skyhawks!!
The "High Top Versace" rapper is a HUGE ATL fan ... and now he's teaming up with Hawks owners Tony Ressler and Grant Hill to join his hometown team's ownership group.
2 Chainz is no stranger to hoops -- he played college ball at Alabama State before focusing on his rap career.
The 41-year-old is also a regular at Hawks games, so it really is a perfect fit.
