Ivar di Waterford (... – 1000) è stato un Re vichingo-gaelico di Waterford dall'anno 969 alla sua morte e di Dublino dal 989 al 993, anno in cui venne scacciato da Sigtrygg Barba di Seta.
Sebbene non vi siano prove definitive a sostegno della tesi, viene inserito nella dinastia degli Uí Ímair di Dublino quale presunto nipote di Ragnall ua Ímair[1][2].
