Dai Duong is Vietnamese in Origin.

Dai Duong is the diacritic-free form of the Vietnamese given name Đại Dương, built from Sino‑Vietnamese elements: đại (大, “great, vast”) and dương (洋, “ocean, open sea”). Together it means “great ocean,” evoking immensity, strength, and a far horizon. The compound functions as a single given name in Vietnam, usually masculine but usable for any gender, and appears in the diaspora without accents.

As a personal name, Đại Dương is a relatively modern choice that grew with late‑20th‑century trends favoring nature and aspirational imagery; families near the coast sometimes adopt it to honor maritime roots. Variants and spellings include Đại Dương, Dai Duong, and the hyphenated Đại‑Dương; nicknames are Dương or Đại, and some adopt Ocean as an English equivalent. Related Vietnamese names with similar seas‑and‑sky imagery include Hải, Biển, Trường Hải, and Thái Dương. Note that Dương elsewhere can mean “sun/yang,” but here it denotes the ocean.
