Nodens (nickname: Lord of the Great Abyss, Nuada of the Silver Hand) is a fictional character, one of the Elder Gods from the pantheon of H. P. Lovecraft's Cthulhu Mythos. His physical form is that of an elderly human male, gray-bearded and hoary, but still vital and strong, with white hair; he's often riding in a chariot formed from a huge sea shell pulled by some great beast. As a hunter, he will chase down evil creatures in the Dreamlands such as Shantaks . He prefers the servants of the Great Old Ones or Nyarlathotep because they offer the best sport and often are very intelligent, not necessarily because he wants to help humans being attacked by them.

And upon dolphins' backs was balanced a vast crenelate shell wherein rode the grey and awful form of primal Nodens, Lord of the Great Abyss... Then hoary Nodens reached forth a wizened hand and helped Olney and his host into the vast shell.

Nodens is served by the Nightgaunts.

Nodens also makes an appearance in the PlayStation Game as a summoned creature.
