Names That Mean Sea or Ocean

65 names

Names that mean sea often come from coastal cultures, and this list gathers them from Wales, Ireland, Hawaii, and the Latin world. Dylan is the Welsh standout: in the Mabinogion, a figure named Dylan takes to the sea as soon as he is born. Murphy comes from an Irish surname usually translated as sea warrior. Hawaiian gives Kai, meaning sea, as well as Makai, meaning toward the sea, and Kailani and Kaylani, which join sea and sky.

Latin mare, the sea, is behind Marina, Marin, and Maren. Marisol blends the Spanish words for sea and sun, and Rosemary descends from the Latin phrase for dew of the sea, the name of the herb that grows along Mediterranean shores. Caspian takes its name from the Caspian Sea and gained a literary layer through the Narnia books.

Ocean, Sailor, and Coral are English word names that make the connection obvious. If your family has ties to the coast, one of these can carry that story quietly. Consider the nicknames as well, since both Marina and Caspian shorten easily in everyday family use.
