The 1971 Kansas City Royals season was their third in Major League Baseball. The Royals had the first winning season (85-76) in franchise history, good enough for second place in the American League West and 16 games behind the Oakland Athletics. Kansas City earning a winning record in its third season was the second fastest of any expansion club in Major League Baseball history up to that point, the 1962 Los Angeles Angels achieved a winning record in their second season. The record would stand until the 1999 Arizona Diamondbacks won the National League West title in their second season.
