Meaning & origin
Fenris first appeared on U.S. birth records in 2011, remaining an exceedingly rare choice. At its peak in 2022, the name still did not crack the top 8,000. By 2025, Fenris ranked 8,910th, given to roughly 1 in 213,510 newborns, and has been declining in use since 2022. The name draws directly from Norse mythology, where Fenrir is the fearsome wolf destined to fight the gods. It has not been recorded in any U.S. state's top names, reflecting its niche appeal among families drawn to mythological or fantasy-inspired names.
Fenris is a name used primarily in modern contexts, drawn from Norse mythology where Fenrir is a monstrous wolf. The name may be related to the Old Norse word 'fen', meaning 'fen' or 'marsh', or to a verb meaning 'to ferry'. Its use as a given name is a modern development, likely inspired by mythological and fantasy literature.
