Incakujira (meaning Inca whale) is a genus of rorqual whales that lived during the Late Miocene epoch in what are now the coasts of Peru, about 8 million to 7.3 million years ago. It contains two species, Incakujira anillodefuego and Incakujira fordycei. The type species, I. anillodefuego, was named and described in 2016. The second species was described in 2024. All known specimens have been found in the sediments of the Pisco Formation of Peru, which dates to the Late Miocene.

Paratype specimen

Incakujira differs from other rorquals (fossil and extant) in having a less attenuated rostrum and the features of the maxilla, supraorbital, and remainder of the cranium. Kujira in the genus name means "whale" in Japanese.[1][2]
