Joseph W. Graboski (January 15, 1930 – July 2, 1998) was an American basketball player who spent 13 seasons in the NBA. He was the third player to enter the NBA without having played in college: (Tony Kappen and Connie Simmons being the first two prep-to-pro players). A star at Tuley High School in Chicago, Illinois, the 6'6" power forward began his professional career with the hometown Chicago Stags, with whom he played from 1949 to 1950.
