Gisela Marie Augusta Richter (14 or 15 August 1882 – 24 December 1972) was a British-American classical archaeologist and art historian.

At Girton, Richter's six closest friends included Lady Dorothy Georgiana Howard, the daughter of the 9th Earl and "Radical Countess" of Carlisle, and future candidate for Roman Catholic Sainthood Anna Abrikosova.

[3] Richter left Girton in 1904 without a degree, since women at the time could not graduate, and she spent a year at the British School at Athens between 1904 and 1905.

As author of numerous popular books on classical art, she had a great influence on the general public's understanding and appreciation of the subject.

Writing 30 years after Richter's death, Camille Paglia paid tribute to her "for her clarity and rigor of mind; her fineness of sensibility and connoisseurship; her attention to detail and her power of observation and deduction; her mastery of form and design".
