Édouard Alexandre Sain (13 May 1830 - 26 June 1910) was a French painter whose works included historical and genre subjects as well as portraits.
Sain was strongly interested in antiquity.
He first settled at Écouen, where he painted various rustic scenes in the plein air style, but experimented with other styles.
His paintings from this period include Vénus et l'Amour, a group of chimney sweeps and a historical painting of the period of Louis XV.
