Meaning & Origin of Dylan

Dylan is a Welsh name derived from the elements "dy," meaning "great," and "llanw," meaning "tide" or "flow," giving it the meaning "son of the sea" or "great tide." In Welsh mythology, Dylan Eil Ton (Dylan Son of the Wave) was a sea god who could swim as well as any fish the moment he was baptized in the ocean. The name was relatively uncommon outside Wales until the 20th century, when the Welsh poet Dylan Thomas brought it international attention. The adoption of the name by the American singer-songwriter Bob Dylan (born Robert Zimmerman) further boosted its popularity. Dylan has been a top-50 name in the United States since the 1990s and is widely used across the English-speaking world.
