Saccopharynx berteli is a species of ray-finned fish within the family Saccopharyngidae.

[2] It is known from a single holotype collected from the central Pacific Ocean through an open fishing net at a depth of 1,100 metres (3,600 ft) in 1977.

The individual caught was an immature male with a length of 89.5 centimetres (35.2 in).

[3][1] It has been classified as a 'Data deficient' species by the IUCN Red List as there is little information regarding its population, ecology, distribution, and potential threats.

[1] It differs from the other nine species in the genus in morphometric characters, principally including the extreme elongation of the caudal region (88.5% of TL) compared with 71–82% in the other species.
