The Singapore National Stadium is a multi-purpose stadium in Kallang, Singapore. It serves as the country's national stadium. Opened in 2014, it was constructed on the site of the former National Stadium, which stood from 1973 to 2010. The 55,000-seat facility is the centrepiece of the Singapore Sports Hub, a sports and recreation district that also incorporates nearby Singapore Indoor Stadium and other sporting venues.

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.
