Princess Frederica Amalia of Denmark and Norway (11 April 1649 – 30 October 1704) was the second daughter of King Frederick III of Denmark and Sophie Amalie of Brunswick-Lüneburg, and Duchess of Holstein-Gottorp from 1667 to 1695 as the consort of Duke Christian Albert.

The marriage was unhappy, with Frederica Amalia often tormented by the frequent disagreements between her brother, Christian V of Denmark, and her spouse.

She was reportedly well known to be badly treated by Christian Albert, while the Danish royal family gave her all sorts of personal privileges and proofs of affection.

Her visits to Sweden inspired great parties and festivities at the otherwise strict Swedish court, and were much appreciated.

As her sons were also anti-Danish, the conflict between Denmark and Holstein-Gottorp continued to put her in a difficult position also as a widow; when she died in her residence in Kiel in 1704, a conflict between Holstein-Gottorp and Denmark about the proper way to ring the bells at her funeral almost provoked war between the two states.
