Brita Clara Alice Augusta Florence von Horn (1 April 1886 – 14 February 1983) was a Swedish novelist, dramatist, director and theatre leader.

von Horn started several theatrical groups and was the first person to stage a play by Anton Chekhov in Sweden.

[6][7] As a writer, von Horn made her debut in 1912 with Lucrezia, subtitled "a drama from the days of the Renaissance in three acts".

[1][8] In 1917 her play Kring drottningen had its premiere at the Swedish Theatre with Pauline Brunius and Gösta Ekman in the lead roles.

With Elsa Collin, a close friend with whom she shared a residence for a time and who was also involved in the Dramatist Studio, von Horn co-wrote a play for the group based on her book Aschebergskan på Wittskövle.
