Pervis Ellison is an American former National Basketball Association (NBA) player. Nicknamed "Never Nervous Pervis" for his clutch play with the University of Louisville, after leading Louisville to a national championship, Ellison was the first overall pick in the 1989 NBA Draft. His professional career was largely hindered by injuries, though he won the NBA Most Improved Player Award in 1992.

The NBA's Most Improved Player Award (MIP) is an annual National Basketball Association (NBA) award given to the player who has shown the most progress during the regular season compared to previous seasons. The winner is selected by a panel of sportswriters throughout the United States and Canada, each of whom casts a vote for first, second and third place selections. Each first-place vote is worth five points; each second-place vote is worth three points, and each third-place vote is worth one point. The player with the highest point total, regardless of the number of first-place votes, wins the award. The criteria for selecting the most improved player was initially open-ended, but the NBA clarified in later years that it was intended for an up-and-coming player who improved dramatically and not a player who made a comeback, distinguishing it from the defunct NBA Comeback Player of the Year Award. Since the 2022–23 NBA season, winners receive the George Mikan Trophy, named after the five-time NBA champion.
