The name Moana is a girl's name of Maori, Polynesian origin meaning "Sea". Moana and is often added to lists like Heroine Baby Names and discussed in our forums with posts like "Names on NB that make you go WOW!".
From the experts:
This Maori name, often heard in New Zealand, is an exotic, evocative choice for a sea lover. Moana is a Polynesian sea god and was also an alternate name for the heroine Ofelia in Pan's Labyrinth. Moana may also be a color name for a deep ocean blue ("lanu moana"). Don't be tempted to shorten this name to "Moa" ("chicken").
