Odarius is an uncommon given name of Latin origin, meaning "golden song". It was created as a variant spelling of the name O'Darious, which combines elements from Irish and Welsh naming traditions. Odarius is composed of two parts: 'Odh', derived from the Irish Gaelic word for music or song, and 'darius', inspired by the ancient Persian king Darius I. This unique name offers parents an opportunity to bestow a distinctive moniker upon their child while also conveying a sense of musicality and regal elegance.
The name Odarius had a peak of popularity in the early to mid-1990s with at least five years recording more than six births each year during that period. However, its usage seems to have declined since then, as there were no recorded births between 1997 and 2000, and only three years (2007, 2009, and 2002) with five or more births after that. Overall, the name Odarius has been given to a total of 82 newborns over the recorded period.
