Dillwin is English, Germanic in Origin.

Dillwin is a modern Anglicized respelling of the Welsh name Dilwyn (also seen as Dillwyn), built from the elements dil, interpreted as “faithful/true,” and gwyn, meaning “fair, white, blessed.” The composite sense is “true and fair” or “steadfast and blessed.” While the -win ending suggests English parallels like Edwin or Baldwin, its roots are distinctly Welsh and tied to the widespread gwyn element found in many traditional names.

In use, Dilwyn/Dillwyn appears in Welsh records from the late 19th and early 20th centuries and also as a notable Swansea surname; personal-name use remained localized and modest. Dillwin as a spelling is very rare, emerging in contemporary English-speaking registries as a streamlined, phonetic variant. Related forms and variants include Dilwyn, Dillwyn, Dilwin, and the feminine Dilwen; nicknames range from Dil and Dilly to Wyn.
