Thérèse-Marie-Rosine Geraldy (18 June 1884 – 31 July 1965) was a French portrait artist.

Born at Paris, Geraldy was the daughter of Louis Paul Lucien Geraldy, an artist, by his marriage to Marie-Anne-Elizabeth Delsarte, a drawing mistress, and was one of four children. She was a granddaughter of the musician François Delsarte, a cousin of the sculptor Maxime Real del Sarte, and related to the composer Georges Bizet. Educated at the Académie Julian^[1] by Marcel Baschet and Henri Royer, she was also a pupil of her aunt Marie Magdeleine Real del Sarte. As a painter, she specialized in portraiture.^[2]

In 1910 she was awarded the Prix Galimard-Jaubert, worth the substantial sum of 4,800 Francs payable over four years.^[3] In 1912 she painted Lord de Saumarez, of Guernsey.^[4] Other subjects included Helen Templeton Pogue, the Duchess of Nemours, and the Countess Rosario Schiffner de Larrechea de Zubov.^[2]
