Antoinette Thérèse Elfforss (née Öberg; 30 November 1823 – 16 April 1905) was a Swedish stage actress and theatre director.

[1] [2] Thérèse Elfforss was born in Stockholm, the daughter of the factory owner Anders Öberg and Maria Elisabeth Kannström.

In 1847, she married the actor Lars Erik Elfforss (1817-1869), director of his own recently formed theater company.

[6] Thérèse Elfforss enjoyed great respect during her career, particularly in her capacity as a director: As director, she focused on Nordic plays, such as Swedish plays by F. A. Dahlgren, C. Axel Anrep, Emilie Lundberg, but also Lorentz Dietrichson, Bjørnstjerne Bjørnson and Ibsen.

When the Lindeberg company was dissolved in 1893, she retired with her son Julius Erik Engelbrekt Elfforss (1847- 1925) to Stockholm where she died in 1905.
