Ronnie Brewer (born March 20, 1985, in Portland, Oregon) is an American professional basketball player for the Utah Jazz of the National Basketball Association. The Utah Jazz selected him with the 14th pick of the 2006 NBA Draft. Brewer played collegiately at the University of Arkansas, where his father Ron Brewer was a star in the late 1970s. Brewer is known for having an unorthodox shooting technique, the result of a childhood water slide injury.

At Arkansas, he averaged 18.4 points, 4.8 rebounds, 3.3 assists, 2.6 steals, and 0.5 blocks. He also was 51–151 from three point range and shot 75% from the free throw line.

Brewer was the 14th pick in the 2006 NBA Draft. Brewer saw very limited playing time in his 2006–07 rookie season with Utah, appearing in only 56 games. However, after a strong performance in the 2007–08 preseason, he assumed the role of Utah's starting shooting guard. By mid-November 2007, he was averaging double figures in points and was among the NBA leaders in steals. He was later selected to play in the 2008 Rookie-Sophomore Game. On February 28th, 2009 Brewer recorded a career high 26 points, along with 7 boards and 4 steals against the Sacramento Kings.
