Tropicana Field (commonly known as the Trop) is a multi-purpose domed stadium located in St. Petersburg, Florida, United States. The stadium has been the ballpark of the Tampa Bay Rays of Major League Baseball (MLB) since the team's inaugural season in 1998. The stadium is also used for college football, and from December 2008 to December 2017 was the home of the St. Petersburg Bowl, an annual postseason bowl game. The venue is the only non-retractable domed stadium in Major League Baseball, making it the only year-round indoor venue in MLB. Tropicana Field is the smallest MLB stadium by seating capacity when obstructed-view rows in the uppermost sections are covered with tarps as they are for most Rays games.

Tropicana Field opened in 1990 and was originally known as the Florida Suncoast Dome. In 1993, the Tampa Bay Lightning moved to the facility and its name was changed to the ThunderDome until the team moved to their new home in downtown Tampa in 1996. In October 1996, Tropicana Products, a fruit juice company then based in nearby Bradenton, signed a 30-year naming rights deal.
