Vampalus is a genus of cetotheriid mysticete from Miocene (Tortonian) marine deposits in the Russian Caucasus. The type species, V. sayasanicus, is based on PIN 5341/1, a complete skeleton. The cetotheriid Eucetotherium helmersonii was mistakenly assigned to Vampalus by Tarasenko and Lopatin, who were unaware that Kellogg (1931) fixed "Cetotherium" helmersonii as the Eucetotherium type species.
