Kaminsky averaged 18.7 points and 8.0 rebounds while shooting 54.9 per cent from the field and 41.5 per cent from 3-point range as the Badgers ran up a 35-3 record and won the Big Ten regular season and tournament titles.
"Frank the Tank'" is the first Wisconsin player to win the award, which started in 1961. He is the third from the Big Ten in the last six seasons, joining Ohio State's Evan Turner in 2010 and Michigan's Trey Burke in 2013.
Kaminsky received 58 votes Friday from the 65-member national media panel that selects the weekly Top 25. Duke freshman Jahlil Okafor received five votes and Kentucky's Wille Caulaey-Stein and Notre Dame's Jerian Grant had one each.
