The Black-and-chestnut Eagle (Spizaetus isidori) is a South American species of bird of prey in the Accipitridae family.

They overlap in range with several other large forest eagles, including Solitary Eagle and possibly other Spizaetus eagles, but no interactions have been reported and the Black-and-chestnut Eagle is believed to be normally the top avian predator in its range.

It is sometimes called Isidor's Eagle.
