Eva Sophie Piper, née Eva Sophie von Fersen (30 March 1757 – 2 February 1816, Löfstad Slott), was a Swedish countess and lady in waiting. She was the daughter of count Axel von Fersen the Elder and Hedvig Catharina von Fersen and the sister of Axel von Fersen the Younger, Hedvig Eleonora von Fersen and Fabian von Fersen (1762–1818). She is foremost known for her close friendship with Queen Hedvig Elizabeth Charlotte, who dedicated her famous diary to her.

As a member of one of the most powerful noble families in Sweden, Sophie von Fersen often participated in court life, though she never served as hovfröken (maid of honor) prior to her marriage, which was otherwise common for a person of her status: both her cousins, Ulla von Höpken and Augusta von Fersen served at court prior to their marriage.

Sophie von Fersen was described as a beauty before her marriage. In 1774, she received a proposal from Duke Frederik Adolf, the king's youngest brother and third in line to the throne, who had previously unsuccessfully proposed to her cousin Ulrika von Fersen.

Her father forbade the marriage, since he had no wish to bind his family to the royal family. Both Sophie and her father feared that she would have been humiliated by the King and the Queen Dowager, who both disliked the match. An attempt to elope was prevented by the Duchess Charlotte. In 1777, Sophie von Fersen married chamberlain count Adolf Ludwig Piper (1750–1795).
