Anna Margareta von Haugwitz ( 16 January 1622 in Calbe (Saale) - 20 March 1673 in Stockholm), was a German noble, married to the Swedish count, statesman and military commander Carl Gustaf Wrangel.
Anna Margareta von Haugwitz was a poor orphan from the untitled lower German nobility when she, as a ward of the German Elisabet Juliana of Erbach, who married the Swedish commander Johan Banér in 1636, met Carl Gustaf Wrangel in the Swedish military camp. The couple fell in love and married for love in 1640, which was unusual and controversial and aroused attention - Wrangel was a member of the most powerfull Swedish nobility and his family disproved because she was of the untitled nobility as well as poor. The relationship between the couple was described as happy. After the Thirty Year's War, she lived mainly at the estates of Wrangel in Swedish Pomerania. At her death, she provided a sum of money to her birth city of Calbe, to be handed out every year at the date of her birth.
