The Assistens Cemetery (Danish: Assistens Kirkegård) is founded in 1757 (inaugurated 1760) and located in the Nørrebro section of Copenhagen, Denmark. It is sometimes called the Nørrebro Cemetery, and is a popular place for people to take a stroll, look at the old graves and monuments, and to have a picnic. A flea market operates along its walls every Saturday from May to October. The yellow walls of the cemetery, especially the one facing Nørrebrogade has in recent years become the target of many graffiti painters.
The cemetery is one of five run by Copenhagen Municipality. The other cemeteries are Vestre Cemetery, Brønshøj Cemetery, Sundby Cemetery, and Bispebjerg Cemetery.
Among the notables interred here are several African-American jazz musicians who made Copenhagen their home.
