Kevin Austin Millwood (born December 24, 1974) is an American former professional baseball pitcher. He played in Major League Baseball (MLB) for the Atlanta Braves, Philadelphia Phillies, Cleveland Indians, Texas Rangers, Baltimore Orioles, Colorado Rockies and Seattle Mariners.

While with the Braves, Millwood was part of a pitching rotation which featured Greg Maddux, Tom Glavine and John Smoltz. In 1999 he was selected to his only All-Star Game and helped lead the Braves to the 1999 World Series and two seasons later the 2001 National League Championship Series. As a member of the Indians, his 2.86 ERA led all American League pitchers. In 2012, Millwood became the 67th pitcher to record 2,000 career strikeouts.

Millwood was raised by Kathy Coplen and Bill Millwood in Bessemer City, North Carolina. He attended Bessemer City High School where he played baseball, basketball and football. As a basketball player, he scored 1,000 points for the Bessemer City Yellow Jackets. Milwood missed the beginning of every high school baseball season in order to finish the basketball season and did not expect to be drafted by a professional baseball team out of high school.

Millwood was drafted by the Atlanta Braves in the 11th round of the 1993 MLB draft. After four years in the minors, Millwood made his debut with the Atlanta Braves on July 14, 1997. A year later, he won 17 games. Millwood formed a part of the Braves' star pitching rotation, which also consisted of Greg Maddux, John Smoltz and Tom Glavine. According to Nate Silver, the 1997 Braves starting rotation was the best in the history of baseball as of the 2010 season.

In 1999, Millwood posted career-highs in wins (18, also achieved in 2002), earned run average (2.68), strikeouts (205) and WHIP (0.996). He finished third in the National League Cy Young Award voting (losing to the Arizona Diamondbacks' Randy Johnson) and 26th on the National League MVP ballot. He was selected as an All-Star in 1999, his only appearance in the Midsummer Classic.

Before the 2003 season, Millwood was traded by the Braves to the Philadelphia Phillies for catcher Johnny Estrada in order to cut their payroll in the midst of economic difficulties. He went 14–12 with his new team, including throwing a no-hitter against the San Francisco Giants on April 27 coming in the Phillies' final season at Veterans Stadium (this was one of only two no-hitters ever thrown at the now-demolished stadium, both coming against the San Francisco Giants). He also led the majors in stolen bases allowed, with 41.

In 2005, Millwood signed a one-year contract as a free agent with the Cleveland Indians. He came back from injury well, leading the American League in ERA (2.86). However, he managed a record of only 9–11, due to poor run support. In 2005, Millwood again led the majors in stolen bases allowed, with 33. He finished tied for sixth in balloting for the AL Cy Young Award.

On December 26, 2005, the Texas Rangers signed Millwood to a five-year, $60 million deal.
