| Class: | Actinopterygii |
| Order: | Polymixiiformes Rosen & Patterson, 1969 |
| Family: | Polymixiidae T. N. Gill, 1862 |

The beardfishes consist of a single extant genus (Polymixia) in a small family (Polymixiidae) of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. At present they are classified in their own order Polymixiiformes,[1] but as Nelson says, "few groups have been shifted back and forth as frequently as this one".[2] For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance.[3]
They are found in tropical and subtropical waters of the Atlantic, Indian and western Pacific Ocean. They are bottom-dwelling fish, found down to about 800 metres (2,600 ft) depth. Most are relatively small fish, although one species is over 40 centimetres (16 in) in length.[3]
