Maria Anna Angelika/Angelica Katharina Kauffmann (October 30, 1741 – November 5, 1807) was a Swiss-Austrian painter.

She was born at Chur in Graubünden, Switzerland, but grew up in Schwarzenberg in Vorarlberg/Austria where her family originated. Her father, Johann Josef Kauffmann, was a poor man and mediocre painter, but apparently very successful in teaching his precocious daughter. She rapidly acquired several languages, read incessantly, and showed marked talents as a musician. Her greatest progress, however, was in painting; and in her twelfth year she had become a notability, with bishops and nobles for her sitters. In 1754 her father took her to Milan. Later visits to Italy of long duration followed: in 1763 she visited Rome, returning again in 1764. From Rome she passed to Bologna and Venice, being everywhere feted and caressed, as much for her talents as for her personal charms.

Writing from Rome in August 1764 to his friend Franke, Winckelmann refers to her exceptional popularity. She was then painting his picture, a half-length, of which she also made an etching. She spoke Italian as well as German, he says; and she also expressed herself with facility in French and English, one result of the last-named accomplishment being that was a popular portraitist for English visitors to Rome. "She may be styled beautiful," he adds, "and in singing may vie with our best virtuosi." While at Venice, she was induced by Lady Wentworth, the wife of the English ambassador, to accompany her to London. One of her first works was a portrait of David Garrick, exhibited in the year of her arrival at "Mr Moreing's great room in Maiden Lane." The rank of Lady Wentworth opened society to her, and she was everywhere well received, the royal family especially showing her great favour.

Her firmest friend, however, was Sir Joshua Reynolds. In his pocket-book, her name as Miss Angelica or Miss Angel appears frequently, and in 1766 he painted her, a compliment which she returned by her Portrait of Sir Joshua Reynolds. Another instance of her intimacy with Reynolds is to be found in her variation of Guercino's Et in Arcadia ego, a subject which Reynolds repeated a few years later in his portrait of Mrs Bouverie and Mrs Crewe.
