Anna Maria Hjärne née Ehrensvärd (1718-1798) was a Swedish courtier, Chief Court Mistress to the queen of Sweden, Sophia Magdalena of Denmark, from 1766 to 1777.
Born to Johan Jacob Ehrensvärd and Anna Maria Mannerheim, she married riksråd count Gustaf Adolf Hjärne in 1739.
[1] The appointment was however mostly formal: it was understood that Hjärne would only serve during grander occasions, and that the office would in practice be performed by her deputy (first Ernestine Palmfelt, from 1767 Charlotta Sparre).
[3] King Gustav III was informed of this and confided in Axel von Fersen the Elder that he was contemplating to divorce the queen for pro-Danish plots and adultery with riksråd Fredrik Ribbing, who was known to court her, and the Danish envoy baron Rosencrone, who forwarded letters from her to Denmark.
When the royal couple consummated their marriage with the assistance of Adolf Fredrik Munck in 1775, the king reportedly apologized to the queen for believing Hjärne's story.
