The Royal Danish Playhouse (Danish: Skuespilhuset) is a theatre building for the Royal Danish Theatre, situated on the harbour front in the Frederiksstaden neighbourhood of central Copenhagen, Denmark. It was created as a purpose-built venue for dramatic theatre, supplementing the theatre's old venue from 1874 on Kongens Nytorv and the 2004 Copenhagen Opera House, which are used for ballet and opera.

The Royal Playhouse is designed by the Danish architectural practice Lundgaard & Tranberg and received a RIBA European Award in 2008 for its architecture.
