Alexandre-Louis Leloir (14 March 1843 – 28 January 1884) was a French painter specializing in genre and history paintings.

Leloir received his early art education from his parents and his maternal grandfather, Alexandre Colin, who had been a pupil of Girodet.

In 1860, Leloir entered the École des Beaux-Arts and made several attempts to win the prestigious Prix de Rome.

In 1861, he won a Second Grand Prix with The Death of Priam (Museum of Art and Archeology, Guéret),[1] then again in 1862, 1863, and again won a Second Grand Prize in 1864 with Homer on the island of Scyros (Unterlinden Museum, Colmar).

His work The Fight of Jacob with the Angel (Roger Quilliot Art Museum in Clermont-Ferrand) presented at the Salon of 1865 is an example of his virtuosity.
