Kekenodon is an extinct kekenodontid early whale from the Late Oligocene (Chattian) of New Zealand.

Measuring 8–9 m (26–30 ft) long, it was a large raptorial whale which hunted marine mammals and penguins.

[1] Although at times classified as a basilosaurid, mysticete, or odontocete, recent work suggests that it represents a phylogenetic intermediate form between Basilosauridae and Neoceti.

Kekenodon was considered a member of the basilosaurid subfamily Dorudontinae in the classic monograph on Archaeoceti by Kellogg (1936).

[3] Phylogenetic analysis suggests that Kekenodon is the "latest-surviving archaeocete, sister-taxon to the Neoceti.
