Butler hired assistant Brandon Miller as its new coach.
Miller replaces Brad Stevens, who was hired by the Boston Celtics to be their new coach earlier in the week.
Butler only took three days to make the hire. The school also considered Michigan assistant LaVall Jordan, who was reportedly considered the leading candidate.
Butler will begin play in its first season in the Big East this winter.
"I am confident that Brandon will carry on the Butler University basketball tradition of excellence, especially as we make the transition to the Big East Athletic Conference," Butler athletic director Barry Collier said in a statement. "As a player, assistant coach, and person, Brandon has exemplified the Butler Way and brings a blend of energy, talent and integrity to this role. With Brandon's leadership, Butler is well positioned to expand upon the success of the last few years."
It is Miller first head coaching job. The 34-year-old graduated from Butler in 2003 and helped the Bulldogs win three Horizon League titles and scored more than 1,000 points in his collegiate career.
Miller has worked as an assistant for Butler, Ohio State and Illinois.
