Armenian Church Youth Organization World (ACYOWorld)

ACYOWorld — the Armenian Church Youth Organization World, known in Armenian as ՀԵՀԵՄ — runs the central office coordinating Armenian Church youth unions across dioceses and communities abroad.

Its work centers on programs rather than a single site: diocesan youth exchanges (a 2026 visit brought around 200 members of the Aragatsotn diocese youth unions to the Gugark diocese), Armenian-language courses for Vrahay (Armenians of Georgia) youth held at the Mother See, an annual sports gathering for the US Western Diocese, and organized pilgrimages. The organization also produces a media project called "Երիտասարդի Մատյան" (Youth's Journal).

Karekin II, Catholicos of All Armenians, is listed as founder-president of ACYOWorld. Archbishop Hovnan Terteryan and Fr. Toma Khachatryan serve as its spiritual leaders.

The office is in Yerevan, roughly 1 km northeast of the city center in straight-line distance.
