Valby is one of the 10 official districts of Copenhagen, Denmark. It is in the southwestern corner of Copenhagen Municipality, and has a mixture of different types of housing. This includes apartment blocks, terraced housing, areas with single-family houses and allotments, plus the remaining part of the old Valby village, around which the district has formed, intermingled with past and present industrial sites.
Valby Hill marks the boundary between Valby and the — more central and more urban — neighbouring Vesterbro district. The expression "west of Valby Hill" is in Danish often used as a metonym for "the provinces" or "outside Copenhagen". Separated from the rest of Copenhagen by Vestre Cemetery, Denmark's largest cemetery, towards Vesterbro/Kongens Enghave and Søndermarken-Frederiksberg Gardens towards Frederiksberg, the Carlsberg brewery site, and areas of low density, Valby retains a certain air of 'independence', or isolation, even today. With the progressing redevelopment of the Carlsberg area into a new lively, high-density neighbourhood, this is likely to change. Other former industrial sites are also under redevelopment and Valby is today one of the districts in Copenhagen with the fastest growing population.
