Henriette Rénard (b. about 1685 - d. after 6 June 1720), was a mistress of Augustus the Strong, King of Poland and Elector of Saxony.
She was the daughter of André Rénard, a wine merchant from Lyon, and an unknown mother who was perhaps the sister of Henri Duval. This may explain why some sources call her Henriette Rénard-Duval. She had two brothers: Jan Baptiste and Benedict.
In 1706, she met August the Strong in Warsaw, when her father had a saloon. Most historians agree that at first, Henriette did not know her lover's true identity.
During the first sixteen years of Anna Karolina's life, she lived with Henriette in complete obscurity without her father's recognition or support. Nevertheless, in 1723, August finally met her and, on 19 September 1724, recognized her as his daughter, creating her Countess Orzelska. Apparently, Henriette never saw her daughter again after this.
The circumstances of her later life and death are unknown.
