Henriette Jacotte Cappelaere was a French painter active from 1846 until 1859.
Little is known of Cappelaere's life, although she warranted an entry in Émile Bellier de La Chavignerie [fr]'s Dictionnaire Général des Artistes de l'école française depuis l'origine des arts du dessin jusqu'à nos jours in 1882.
In 1850 she lived at 22, rue Godot-de-Mauroy, which would later become part of the 9th arrondissement of Paris.
That year she exhibited her best-known works at the Salon; one was a portrait of Harriet Howard, mistress of Napoleon III, and one was a painting of his dog, Ham.
Today both pieces are in the collection of the Château de Compiègne.
