Fie Carelsen, stage name of Sophia de Jong (April 5, 1890 – July 21, 1975), was a Dutch actress.

She made her debut in the Dutch East Indies with the Kimmel & Chrispijn Company. Back in the Netherlands, she made her debut with Dr Willem Royaards' N.V. Tooneel as Blanche in Shaw's "Widower's Houses", staying with this company until 1914. After that she joined the Koninklijke Vereeniging Het Nederlandsch Tooneel. From 1917 Eduard Verkade was in charge of this company; under his direction, her talent came to full development and she gradually became a widely recognised stage actress. On her 25th anniversary in 1932, she played the title role in the play Mata Hari. In 1934 she joined the cast of feature film Malle Gevallen.

She was married to Dutch cabaret artist Jean-Louis Pisuisse from 1913 to 1920. She acquired ownership of Pisuisse's grave in 1970 and stated in her will that she wished to be interred in his grave. In 1976 the Pisuisse Prize was established from her estate, for the best theatrical performance by a pupil of the Academie voor Kleinkunst.
