Princess Anna Petrovna Lopukhina () (8 November 1777 – 25 April 1805) was a royal mistress to Emperor Paul of Russia. In 1798, she replaced Catherine Nelidova as the chief mistress. Family She was the daughter of Prince Pyotr Vasilyevich Lopukhin, from the Lopukhin family, one of the oldest families of Russian nobility, which owed its distinction to Eudoxia Lopukhina's marriage to Peter the Great and of which the unfortunate Natalia Lopukhina was also a member. Her mother was Praskovia Ivanovna Levshina. Royal mistress Lopukhina met Emperor Paul during a ball in 1796. His tenderness towards her was noted by a court faction which hoped to use her as a remedy against the influence of the Empress Maria Feodorovna.

After the sovereign acquiesced, Gagarin was recalled from Alexander Suvorov's army then fighting in Italy and the wedding took place on 11 January 1800. The marriage was also to protect her from public spite. Later life and death A year later, the Emperor was murdered and the Gagarins proceeded to Turin, where her husband Prince Gagarin was appointed ambassador. Theirs was a marriage of convenience, and he seems to have had little reason for grief when she died of consumption in 1805 at the age of 27. Anna's body was brought back to the Russian capital, where her
