Eva Marianna Besnyö (Budapest, April 29, 1910 - Laren, December 12, 2003) was a Hungarian-Dutch photographer.
Until the Second World War she did a lot of portrait photography, but her photographing of architecture was also of interest. After her two children had grown older, she started photographing again. In the early 1970s she focused mainly on capturing the actions of Amsterdam feminists, particularly the Dolle Mina group. In 1985, the Annie Roman Prize was awarded to Besnyö. In 1994 she received the Piet Zwart Prijs.
In old age she had to stop photographing because of problems with her eyes. In the last years of her life she lived in the Rosa Spier House in Laren where she died in 2003 at the age of 93.
