玛波努斯（英语：Maponos）。古罗马神祇之一。主要出现于西欧（今法国、英国）等地区。凭借在威尔士与高卢的相关神话作品之中象征青春与活力而影响深远。

In ancient Celtic religion, Maponos or Maponus ("Great Son") is a god of youth known mainly in northern Britain but also in Gaul. In Roman times he was equated with Apollo.

The Welsh mythological figure Mabon ap Modron is apparently derived from Maponos, who by analogy we may suggest was the son of the mother-goddess Dea Matrona. The Irish god Aengus, also known as the Mac Óg ("young son"), is probably related to Maponos, as are the Arthurian characters Mabuz and Mabonagrain.
