Arrowhead Stadium is a stadium located in Kansas City, Missouri, and home to the National Football League's Kansas City Chiefs. The stadium was the former home of the Kansas City Wizards of Major League Soccer from 1996 to 2007. It is part of the city's Truman Sports Complex (together with Kauffman Stadium). Fans occasionally refer to the stadium as The Red Sea or simply Arrowhead. The stadium is commonly referred to as the "Home of the CHIEFS" at the beginning of every home game during the singing of the national anthem.

Arrowhead has long held a reputation for being one of the loudest outdoor stadiums in the NFL due to the exuberance of the Chiefs' fans. Fan generated noise was once measured at 116 decibels[5] by the Acoustical Design Group of Mission, KS. This contributes to the unique "atmosphere" of the stadium, which Sports Illustrated quoted as the reason they gave Arrowhead Stadium the title of being the "Toughest Place to Play" for opposing teams. They explained, "When the Chiefs are having a bad season, they’re tough to beat at Arrowhead. When they’re having a good season, they’re unbeatable. With the scent of barbecue in the air and a sea of red in the stands, Kansas City is the best football atmosphere in the country."

As of the end of the 2007 NFL season, Arrowhead Stadium has a consecutive sell-out record of 149 games (17 full seasons) dating back to the home opener on September 1, 1991 (14-3 victory vs. Atlanta). The Chiefs have a 104-40 home record at Arrowhead stadium since 1990, the best in the NFL.
