Moray eels, or Muraenidae, are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water. The English name, from the early 17th century, derives from the Portuguese moréia, which itself derives from the Latin mūrēna, in turn from the Greek muraina, a kind of eel.

Gymnothorax is a genus of fish in the family Muraenidae found in Atlantic, Indian and Pacific Ocean. With more than 120 species, it the most speciose genus of moray eels.

Smith (2012) noted that Gymnothorax as currently recognized is polyphyletic, but cautioned that comparative studies are needed before action is taken to resurrect generic synonyms of Gymnothorax.
