Olloudius (Olludius, Ollodagus) is a Celtic god worshipped in Britain and Gaul. He is likely to have been considered a protector deity with wide-ranging influence.
He was sometimes identified by the Romans with their god Mars by way of the interpretatio romana.
Olloudius received votive and dedicatory offerings from his worshippers; otherwise little is known of the specifics of his cult.
Olloudius’ name may have been derived from the Proto-Celtic *olyo or “all” and *dewo” or “god,” making him a god of all things.
Olloudius was worshipped over a broad area, ranging from what is now Gloustershire, England to southern France.
