Lakers general manager Mitch Kupchak said that "Mike was the right person at this time to lead the Lakers forward."
Kupchak cited the make-up of the roster and D'Antoni's style of play as reasons for his hiring.
The Lakers website reports that owner Dr. Jerry Buss, executive vice president Jim Buss and Kupchak both agreed that D'Antoni was the best coach for the team.
D'Antoni had an opportunity to coach Bryant as an assistant with Team USA in the 2012 Olympic games.
The team is expected to have a press conference to introduce D'Antoni on either Tuesday or Wednesday.
