Ebba Wilhelmina Modée (October 4, 1775, Karlskrona, Blekinge County, Kingdom of Sweden – March 23, 1840, Eksjö, Jönköping County), was a Swedish noblewoman and courtier, a love interest and potential wife of King Gustav IV Adolf of Sweden.
Modée was a maid of honor to Duchess Hedvig Elisabeth Charlotte (born a princess of Holstein-Gottorp), wife of the future Charles XIII, between 1794 and 1801, and accompanied her on her trip to Germany and Austria in 1798–1799.
In 1795, despite his recent engagement to Duchess Louise Charlotte of Mecklenburg-Schwerin, Gustav IV Adolf fell in love with Modée.
Several courtly and political factions worked to prevent the King's marriage to a Swedish woman in favour of a marital alliance with a foreign power.
In 1801, Modée married a fellow courtier, General Lieutenant Count Axel Otto Mörner af Morlanda (1774–1852), with whom she had been in love for a long time.
