Milan confirmed the signing of the 30-year-old on their official website on Thursday and it was quickly followed up with some photos of the Italian international in action.
The Italian giants paid Serie A rivals Juventus £35million for the defender's services, with the player penning a five-year deal.
Bonucci is one of ten new arrivals at the San Siro this summer as the club's new Chinese owners flex their considerable financial muscle.
Bonucci will be hoping he can help the club become a member of European football's elite once again.
