Osa is a unique and distinctive given name of African origin, specifically from the Yoruba culture. It is derived from the Yoruba word 'Oṣa', which translates to 'wealth'. In Yoruba mythology, Oṣa is the deity of wealth, prosperity, and fortune, often associated with the color gold.
"Osa was a popular baby name between 1914 and 1929, with peaks in the mid-1910s and late 1920s. After a gap of nearly nine decades, it resurfaced again in 2017."
