Wangsa O'Neill (Bahasa Irlandia: Ó Néill) merupakan nama keluarga keturunan Gaelik Irlandia, yang memegang posisi dan gelar terkemuka di Irlandia dan di wilayah lain. Sebagai penguasa Wangsa Cenél nEógain, mereka dikenal sebagai keluarga paling terkemuka di Uí Néill Utara, bersama dengan O'Donnell dan O'Doherty. O'Neills berpendapat bahwa leluhur mereka adalah raja-raja Ailech selama abad pertengahan awal, sebagai keturunan Niall Noígíallach.
