Máel Sechnaill mac Máele Ruanaid (wafat 27 November 862) adalah Raja Tinggi Irlandia. Annal Ulster menggunakan gelar Irlandia Lamarí hÉrenn uile, yang artinya "raja seluruh Irlandia", saat mengabarkan kematiannya, untuk membedakan Máel Sechnaill dari Raja-Raja Tara yang hanya disebut Raja Tinggi Irlandia pada sumber-sumber seperti Annal Empat Masters atau Foras Feasa ar Éirinn karya Geoffrey Keating.
