Annagh Hill (Gaelic: An tEannach, meaning "marsh" or "bog") is a hill in the north of County Wexford, Republic of Ireland.
Annagh Hill is separated from Croghan Mountain to the north by the "Wicklow Gap", not to be confused with the Wicklow Gap in County Wicklow. Except for the southeastern face (see photo) it is covered in coniferous forest.
It overlooks the villages of Monaseed and Hollyfort to the south, across the valley of the Blackwater stream.
