Maponus is Celtic in Origin.

Maponus is a Brittonic/Gaulish theonym turned rare given name, from Proto-Celtic *mapos 'son, youth' plus the intensifying suffix -onos, yielding the sense 'great son' or 'divine youth'. Latin inscriptions from Roman Britain (notably near Hadrian’s Wall and at Ribchester) invoke Apollo Maponus, aligning him with healing, music, and poetic inspiration. Sporadic dedications also occur across the wider Celtic world. The Welsh reflex is Mabon, preserved in medieval literature as the ever-young hero Mabon ap Modron.

Variants and related forms include Maponus/Maponos (Latinized spellings), Mabon (Welsh), and Cornish Mabyn; short forms like Mab are possible. Echoes persist in toponyms such as Lochmaben and Locus Maponi. As a modern given name, Maponus is exceedingly rare but appeals to families seeking a mythic, pan-Celtic heritage. The meaning centers on youthfulness and renewal, and in neopagan circles Mabon names the autumn equinox.
