Valenticarbo is a supposed genus of extinct bird that lived during the Late Pliocene or Early Pleistocene (c. 1.8 mya) of South Asia.

Harrison (1979) erected this genus because he found himself unable to assign a 19th-century plaster cast of a broken tarsometatarsus bone originally retrieved from Siwalik Hills sediments to modern cormorants.

Those that did chided Harrison's decision to assign an undiagnostic and possibly damaged cast as a type specimen of a new genus.

Olson (1985) called it "...very near the acme of zealotry for naming new species of fossil birds.

It is highly doubtful that the genus Valenticarbo could be shown to be valid, even if a specimen of it did exist.
