Henri-Mamert-Onésime Delafond (1805–1861) was a French veterinarian who was director of the Maisons-Alfort veterinary school.

Delafond is remembered for pioneer microscopic research of Bacillus anthracis, the causative organism of anthrax. Also, with microbiologist David Gruby (1810–1898), he performed extensive investigations of Tritrichomonas suis, a parasite found in swine.

In 1842 with Gabriel Andral (1797–1876) and Jules Gavarret (1809–1890), he was co-author of an important treatise on animal blood composition titled Recherches sur la composition du sang de quelques animaux domestiques, dans l’état de santé et de maladie.
