Neptunians are the inhabitants of the planet Neptune.
Several species of sentient humanoid Neptunians have been encountered:
- Carter Hall, the Hawkman, found a Neptunian starship in 1941, and was forced to kill a rampaging Neptunian. This Neptunian was already born talking, had white skin, could emit heat-blasts from his eyes, and would be many feet tall in short time.
- Dr. Mid-Nite was once temporarily stranded on Neptune. The Neptunians seemed have evolved directly from plants: had green leaves instead of hair, pink skin, long fingers, roots in their feet (which they would use for nutrition). It was later revealed that Dr. Mid-Nite had actually traveled to the Neptune of another dimension, in Hyperspace, not the native Neptune of the Earth-Two dimension.
- In 1945, a broken-off piece of the planet Neptune landed on Earth and formed a new continent. Wonder Woman fought some Neptunians there. These Neptunians seemed human, but with very different culture and values, and advanced technology, including Electric Pistols, Water Whips, Unbreakable Nets, Mechanizing Machine (which cause a slave-like state in men by extracting salt from their bodies), Steam Gun, Cranial Subfusing Machines (that would devolve humans into tigeapes) and Atom-splitting Guns. They didn't have any women among them - they create humans from a process using salt water, but only men. They practiced slavery and had a warlike society.
- In an alternative future, Tommy Tomorrow will meet Neptunians in one of his many space adventures.
- In the 31st Century, Ron-Karr, a Neptunian with Earthly ancestors, will be a member of Legion of Substitute Heroes.
- In the 853rd Century, Neptune is patrolled by Aquaman, and is a place where entire cities of living coral gently ride the ocean currents, where aquatic life from all corners of the cosmos schools in harmony.
- At the Future State event, Aquaman (Jackson Hyde) accidentally arrived on Neptune, home planet of a very technologically advanced underwater society.
