Effyn is English, Welsh in Origin.

Effyn is a rare modern given name whose form is strongly influenced by Welsh spelling conventions: ff represents the /f/ sound, and -yn is a common masculine ending. Usage appears sporadically in the late 20th and early 21st centuries, mainly in the UK and other English‑speaking countries, and the name is sometimes chosen for its crisp, contemporary look. It is most often used for boys but can be treated as unisex.

Several etymological routes are proposed. Effyn is frequently interpreted as a Welsh‑styled variant of Evan/Ifan (from John), yielding the meaning “God is gracious.” Others view it as an elaboration of Effie/Effy, a pet form of Euphemia (“well‑spoken”), or compare it to Irish Evin/Éimhín, sometimes glossed “gentle” or “swift.” Variants and near‑forms include Effin, Effan, Efin, Efyn, Evan, Ifan, and Ieuan; common diminutives are Effy and Effie.
