Esplanaden is a street in Copenhagen, Denmark. It extends eastwards from Store Kongensgade and runs along the south side of the city's 17th-century fortress Kastellet and Churchillparken until it reaches the waterfront at Nordre Toldbod, just south of Langelinie, passing Amaliegade, Bredgade and Grønningen on the way. It marks the northern border of the Frederiksstaden district.
