Meaning and history
Possibly meaning “deer friend,” this name is derived from Old Irish oss “deer” and carae “friend,” though it may also come from the Old English name Osgar or its Old Norse cognate Ásgeirr, perhaps introduced to Ireland by Viking invaders and settlers. In Irish legend, Oscar was the son of the poet Oisín and the grandson of the hero Fionn mac Cumhaill. The name was popularized in continental Europe by the 18th-century Scottish poet James Macpherson, and Napoleon, an admirer of Macpherson, suggested Oscar as the second middle name of his godson, later King Oscar I of Sweden. Notable bearers include the Irish writer and humorist Oscar Wilde (1854–1900) and the Brazilian architect Oscar Niemeyer (1907–2012).
Oscar moved from #216 to #223 for boys between 2024 and 2025. Its highest annual birth count came in 2006, with 3,601 births.
