Sigrid Sparre (Sigrid Maria Josefina Ingeborg Richissa Eufemia Ulfhild; 1 September 1825, in Nygård – 17 November 1910, in Stockholm) was a Swedish lady in waiting and noblewoman, known for her relationship with Charles XV of Sweden.
She was the hovfröken (maid of honor) of queen Josephine of Sweden in 1844–1850 and became known for her love affair with Crown Prince Charles.
The queen gave her Catholic confessor, Jacob Lorentz Studach, the task to provide evidence of the affair by catching the couple together.
This was achieved on Tullgarn Palace in 1850, after which Sparre lost her position and was forced to leave court, despite the protests of Charles.
[2] Charles married Princess Louise of the Netherlands in 1850, courted the noblewomen Stani Eketrä and Aurore Palin and had a relationship with first Laura Bergnéhr and then with a relative of Sigrid, Josephine Sparre.
