Meaning and history
From a Latin Roman cognomen meaning “lucky” or “successful,” Félix was taken as an agnomen by the 1st-century BC Roman general Sulla and appears in the New Testament as the name of the governor of Judea who imprisoned Saint Paul. Its favorable meaning made it popular among early Christians, and it was borne by many early saints and four popes. The name has been used in England since the Middle Ages but has been more common in continental Europe; a notable bearer was the German composer Felix Mendelssohn (1809–1847).
Felix rose from #179 to #175 for boys between 2024 and 2025. Its highest annual birth count came in 2024, with 2,090 births.
