Tim Hortons Field, nicknamed "The Donut Box",; is a multi-purpose stadium in Hamilton, Ontario, Canada. Built as a replacement for Ivor Wynne Stadium, Tim Hortons Field is primarily used for Canadian football and soccer, and is the home of the Hamilton Tiger-Cats of the Canadian Football League and Forge FC of the Canadian Premier League. During the 2015 Pan American Games, it was referred to as CIBC Hamilton Pan Am Soccer Stadium. The stadium opened in September 2014, two months after its original anticipated completion date of June 30, 2014.

A multi-purpose stadium is a type of stadium designed to be easily used for multiple types of events. While any stadium could potentially host more than one type of sport or event, this concept usually refers to a specific design philosophy that stresses multifunctionality over specificity. It is used most commonly in Canada and the United States, where the two most popular outdoor team sports—Canadian football or American football and baseball—require radically different facilities. Football uses a rectangular field, while baseball is played on a diamond with a large outfield. Since Canadian football fields are larger than American ones, the design specifications for Canadian facilities are somewhat less demanding. The particular design to accommodate both is usually an oval, although some later designs use an octorad. While building stadiums in this way means that sports teams and governments can share costs, it also presents some challenges.
