Amaliehaven (English: The Amalie Garden) is a small park located between Amalienborg Palace and the waterfront in the Frederiksstaden neighbourhood of central Copenhagen, Denmark.

The park is part of the so-called Frederiksgade axis, the shorter but more distinctive of the two axes on which Frederiksstaden is centred.

Amaliehaven is located on a site where there used to be a shipyard established in 1802 by a wealthy ship-owner named Lars Larsen.

Amaliehaven is a rectangular park built to a stringent, symmetrical design centred on a large fountain to respect and accentuate the Frederiksgade axis which unifies the entire area.

The garden abounds with different varieties of plants and fragrant flowers whose colours and natural shapes create a contrast to the geometrical layout of the park.
