Gwili is Welsh in Origin.

Gwili is a rare Welsh given name drawn from the Afon Gwili, a tributary of the River Tywi in Carmarthenshire. As with many Celtic hydronyms, its ultimate meaning is uncertain, but it is commonly linked to roots denoting “stream” or “flow,” giving the name a nature-rich sense of movement and water. Because it derives from a place-name rather than a gendered personal name, Gwili is used as a unisex choice.

As a personal name, it gained cultural visibility through the Welsh bardic tradition; the theologian and poet William Davies (1878–1952) adopted “Gwili” as his bardic name in honor of the river. Contemporary usage remains uncommon in Wales and the diaspora, appealing to parents seeking a lyrical, distinctly Welsh option. Variants and related forms include the nickname Gwil and the established Gwilym (Welsh for William), which shares sound but a different origin; Anglicized spellings such as Gwylie or Gwily appear.
