Titanotaria orangensis is a late, basal walrus from the Miocene of Orange County, California, and the only recognised species of its genus. It is known from an almost complete skeleton, catalogued as OCPC 11141, that is the best preserved fossil walrus currently known. The fossils were found in 1993 in the Oso Member of the Capistrano Formation at Lake Forest, but they were not described until 2018, when Isaac Magallanes and colleagues published an examination of the skeleton. Unlike much later walruses it had no tusks. It reached a length of about 3.0 metres and weighed around 540 kilograms. The genus name honours the California State University, Fullerton Titans, and the species name means coming from Orange County.
