Kauffman Stadium () (nicknamed "The K") is a ballpark located in Kansas City, Missouri, and the home of Major League Baseball's Kansas City Royals. It is next door to Arrowhead Stadium, home of National Football League's Kansas City Chiefs. Both make up the Truman Sports Complex. The stadium is named for Ewing Kauffman, the founder and first owner of the Royals. It opened in 1973 as Royals Stadium and was named for Kauffman 20 years later on July 2, 1993. Since its last major renovation in 2009, its listed seating capacity is 37,903.
Kauffman Stadium was built specifically for baseball during an era when building multisport "cookie-cutter" stadiums was commonplace. It is often held up along with Dodger Stadium (1962) in Los Angeles as one of the best examples of modernist stadium design.
