Lir or Ler (meaning "Sea" in Old Irish; Ler and Lir are the nominative and genitive forms, respectively) is a sea god in Irish mythology. His name suggests that he is a personification of the sea, rather than a distinct deity. He is named Allód in early genealogies, and corresponds to the Llŷr of Welsh mythology. Lir is chiefly an ancestor figure, and is the father of the god Manannán mac Lir, who appears frequently in medieval Irish literature. Lir appears as the eponymous king in the tale The Children of Lir.

Llŷr (Welsh: Llŷr Llediaith (Welsh pronunciation: [ˈɬɨːr ˈɬɛðjaiθ]); Lleddiaith meaning 'half-speech' or 'half-language') is a figure in Welsh mythology, related to the Irish Ler ('the Sea'), father of Manannán mac Lir. Other than his progeny and odd tidbits, his identity remains obscure.
Llŷr appears as the father of Brân, Brânwen and Manawydan by Penarddun in the Branwen, Daughter of Llyr, the Second Branch of the Mabinogi.
