Sankt Annæ Plads (English: St. Ann's Square) is a public square which marks the border between the Nyhavn area and the Frederiksstaden district in Copenhagen, Denmark. It is a long narrow rectangle which extends inland from the waterfront, at a point just north of the Royal Danish Playhouse at the base of the Kvæsthusbroen pier, until it meets Bredgade. The unusual shape is due to the square's past as a canal similar to nearby Nyhavn.
