Boston's Marcus Morris missed a 14-footer at the buzzer with Khris Middleton's hand in his face to seal a nail-biting win for the Bucks.
Seconds earlier, the 6-foot-11 Antetokounmpo jumped and reached up with his left arm around Boston's Jayson Tatum to put back Malcolm Brogdon's missed layup for the game-winner.
Game 5 is Tuesday night in Boston.
Jaylen Brown had 34 points for the Celtics, while Tatum added 21. Tatum's 18-footer with 52 seconds left gave the Celtics a brief 100-99 lead.
