The spotted eagle ray (Aetobatus narinari) is a cartilaginous fish of the eagle ray family, Myliobatidae. It is found around the world in tropical waters, including the Gulf of Mexico, Hawaii, off the coast of West Africa, the Indian Ocean, and on both coasts of the Americas. The rays are most commonly seen alone, but occasionally swim in groups. Rays are ovoviviparous, the female retaining the eggs then releasing the young as miniature versions of the parent.

Spotted eagle rays are considered near threatened on the IUCN Red List. In the state of Florida in the United States, the fishing, landing, purchasing and trading of spotted eagle ray is against the law. The spotted eagle ray is also protected on the Great Barrier Reef off the eastern coast of Australia.
