The yellow triplefin (Enneapterygius abeli),> also known as the Abel's triplefin in South Africa, is a species of triplefin in the genus Enneapterygius. Males in this species can reach a maximum length of 2.5 centimetres. The blennies are generally bright yellow in colour, and males have black heads. They feed mostly on benthic invertebrates.

In 1960, Wolfgang Klausewitz described the species, originally assigning it to the genus Tripterygion under "T. abeli".{{cite journal | author = Klausewitz, W., 1960 | title = Fische aus dem Roten Meer. III. Tripterygion abeli n. sp. (Pisces, Blennioidea, Clinidae) | journal = Senckenbergiana Biologica | volume = 41 | issue = 1/2 | pages = 11–13}} It was later reassigned to Helcogramma, before being reassigned to Enneapterygius by W. Holleman in 2005.{{cite journal | author = Holleman, W. | year = 2005 | title = A review of the triplefin fish genus Enneapterygius (Blennioidei: Tripterygidae) in the western Indian Ocean, with descriptions of four new species | journal = Smithiana | volume = Bulletin 5 | pages = 1–25}}

The fish is named in honor of Austrian biologist Erich F. Abel (1919-1995) of the University of Vienna, who worked on the ecology and ethology of fishes of the Mediterranean and the Red Sea, and who donated the type specimens from the Red Sea to the Senckenberg Museum.{{cite web | url = http://www.etyfish.org/blenniiformes1/ | title = Order BLENNIIFORMES: Families TRIPTERYGIIDAE and DACTYLOSCOPIDAE | access-date= 27 November 2021 | author1 = Christopher Scharpf | author2 = Kenneth J.
