Shaq's 18-year-old daughter, Amirah O'Neal, announced she's headed to Baton Rouge to play basketball for the Tigers next season ... just months after her big bro, Shareef, committed to LSU.
"I am excited to say that I have decided to commit to being a student athlete at LSU along side my brother @shareefoneal," Amirah said on IG.
"I am Sooooo grateful to spend my next 4 years as a Tiger."
Of course, both O'Neals are following in their father's famous footsteps -- Shaq is an LSU legend who balled out in the Pete Maravich Assembly Center from '89 to '92 before lighting up the NBA.
