Spencer Mason Hawes (born April 28, 1988) is an American professional basketball player who last played for the Milwaukee Bucks of the National Basketball Association (NBA). He was selected by the Sacramento Kings in the 2007 NBA draft and is the nephew of Steve Hawes, a retired NBA player.
Hawes played center at Seattle Prep, an elite college-prep school in Seattle, Washington. The team won the state championship in the 2005–06 season and Hawes was named the tournament MVP. He might have entered the 2006 NBA Draft had the NBA not enacted a new rule requiring players to wait a year after their class graduates from high school. Following the 2005–06 season, Hawes was selected as an Associated Press All-American, McDonald's All-American, Parade All-American, and USA Today All-American. He was also named 2006 Gatorade Boys Basketball Washington Player of the Year and Seattle Times player of the year.
