Margonin was a private town of Polish nobility, administratively located in the Kcynia County in the Kalisz Voivodeship in the Greater Poland Province.

Polish jurist, poet, political and military activist Józef Wybicki, best known as the author of the lyrics of the national anthem of Poland, married Kunegunda Drwęska in Margonin in 1773.

The Polish population was subjected to various crimes, including murders, deportations to Nazi concentration camps and expulsions.
