Boldklubben af 1893, commonly referred to as B.93, is a football club based in Østerbro, Copenhagen, Denmark. The team competes in the Danish 1st Division, the second level of the Danish football league system, after achieving promotion in the 2022–23 season. The club has won nine league titles and one Danish Cup.

B.93 was originally founded as a cricket club on 19 May 1893, and was named Cricketklubben af 1893 at its inception. Football was introduced in 1896, at which point the club adopted its current name. Tennis was added in 1901. The cricket division was later discontinued, but the football and tennis divisions remain among the country's larger clubs by membership.

The club's football division, with 1,834 members, was the fifth-largest football club under DBU Copenhagen in Denmark in 2023.
