Prince Frederick Henry Albert of Prussia[citation needed] (German: Friedrich Heinrich Albrecht; 4 October 1809 – 14 October 1872) was the fifth son and youngest child of King Frederick William III of Prussia and Louise of Mecklenburg-Strelitz.

His parents had fled to East Prussia after the occupation of Berlin by Napoleon, and Albert was born in Königsberg.

In The Hague, on 14 September 1830 Albert married his first cousin Princess Marianne, daughter of King William I of the Netherlands.

They had two sons: As this second union was considered a morganatic marriage, the couple temporarily had to avoid the Prussian court.

Albert acquired a vineyard in Loschwitz near Dresden, Saxony, where he had a residence, Albrechtsberg Castle, erected in 1854.
