Ocucajea is an extinct genus of basilosaurid cetacean from Middle Eocene (Bartonian stage) deposits of southern Peru. Ocucajea is known from the holotype MUSM 1442, a partial skeleton. It was collected in the Archaeocete Valley site, from the of the Pisco Basin about 40.4 to 37.2 million years ago.[1]

The genus was named after the town Ocucaje in the Ica Province near the type locality, and the species after , naturalist, artist, and an important contributor to Peruvian palaeontology.[2]

Ocucajea is smaller than all other dorudontines. It differs from Saghacetus and Dorudon in cranial morphology; in Ocucajea the nasals extends farther posteriorly than the maxillae, and there is no narial process of the frontal like in Saghacetus.[3]
