Meaning and history
Gunnar is derived from the Old Norse name Gunnarr, composed of the elements gunnr, meaning “war,” and herr, meaning “army” or “warrior,” making it a cognate of Gunther. In Norse legend, Gunnar was Brynhildr’s husband, and he had his brother-in-law Sigurd murdered after his wife falsely accused Sigurd of taking her virginity.
Gunnar moved from #598 to #612 for boys between 2024 and 2025. Its highest annual birth count came in 2015, with 825 births.
