Lucas Oil Stadium is a multi-purpose stadium in downtown Indianapolis, Indiana, United States. It replaced the RCA Dome as the home field of the National Football League (NFL)'s Indianapolis Colts and opened on August 16, 2008.The stadium was constructed to allow the removal of the RCA Dome and expansion of the Indiana Convention Center on its site. It is located on the south side of South Street, a block south of the former site of the RCA Dome. The stadium's naming rights belong to the Lucas Oil corporation. The venue also serves as the home for the Drum Corps International Championships.

Architectural firm HKS, Inc. was responsible for the stadium's design, with Walter P Moore working as the Structural Engineer of Record. The stadium features a retractable roof and a large retractable window on one end, allowing the Colts to play both indoors and outdoors. The field surface was originally Field Turf, but was replaced with Shaw Sports Momentum Pro in 2018. The exterior of the new stadium is faced with a reddish-brown brick trimmed with Indiana limestone, similar to several other sports venues in the area, including Gain bridge Fieldhouse, Hinkle Fieldhouse and Fairgrounds Coliseum.
