Anna Margareta Momma née von Bragner (1702–1772), was a Swedish publisher, chief editor and journalist.
Momma was identified as the author behind the Swedish language essay paper Samtal emellan Argi Skugga och en obekant Fruentimbers Skugga (English: 'Conversation between the Shadow of Argus and the unfamiliar Shadow of a Female'), or popularly Samtal (Conversation), which has become her most known work.
In the conversations, the essay promoted freedom of speech, freedom of religion, advocated to translate knowledge to the Swedish language to make it available to more people rather than to restrict most such literature to foreign languages in the universities, and stated that women should also been given higher education and participate in public debate.
Affected strongly by the continental ideas of enlightenment, it was regarded as radical and progressive and came in conflict with the contemporary censorship laws.
In 1772, she died along with her spouse and her remaining son, and the family business was inherited by her daughter Elsa Fought.
