Ulrika "Ulla" Eleonora von Höpken, later von Wright, née von Fersen (24 March 1749 – 17 September 1810), was a Swedish countess and courtier. She is also famous in history as one of "the three graces" of the Gustavian age; three ladies-in-waiting (Augusta von Fersen, Ulla von Höpken and Louise Meijerfeldt) immortalized in the poem Gracernas döpelse by Johan Henric Kellgren, and known profiles of the epoch. She was a leading socialite and trendsetter in contemporary Sweden, and one of the best known profiles of the Gustavian age.
Ulla von Fersen was one of six daughters of the royal Crown Forester count Carl Reinhold von Fersen and the lady-in-waiting Charlotta Sparre. She was as such also the niece of Axel von Fersen the Elder, a leading force within the Caps, and the cousin of the famous Count Axel von Fersen the Younger. Her father was described as "one of the most elegant and spirited gentlemen of his time", and her mother was celebrated for her beauty at the French royal court of Versailles, when she accompanied her aunt and uncle by marriage, Ulla Tessin and the Swedish ambassador to France count Carl Gustaf Tessin, to France.
Both her parents spent their life in service at the royal Swedish court, and Ulla von Fersen, as well as her sisters, served as hovfröken (maid of honour) prior to her marriage. From 1767 to 1770, she served as hovfröken to the Crown Princess, Sophia Magdalena of Denmark.
In 1767, Prince Frederick Adolf of Sweden fell in love with her. In parallel, Prince Charles courted another lady in waiting, Brita Horn, with the same intent.
