Cheirolepis (from Greek: χείρ kheír, 'hand' and Greek: λεπίς lepis 'scale') is an extinct genus of ray-finned fish that lived in the Devonian period of Europe and North America. It is the only genus yet known within the family Cheirolepidae and the order Cheirolepiformes. It was among the most basal of the Devonian actinopterygians and is considered the first to possess the "standard" dermal cranial bones seen in later actinopterygians.

| - Cheirolepis ist ein Knochenfisch aus dem Mitteldevon. Die ersten fossilen Überreste dieser Gattung wurden im Old-Red-Sandstein in Schottland gefunden, weitere Fossilien stammen aus Kanada. Cheirolepis ist der erste gut bekannte Strahlenflosser und wahrscheinlich die primitive Schwestergruppe aller anderen bekannten Strahlenflosser. Frühere Angehörige der Klasse sind nur aus dem späten Silur in Form einzelner Schuppen überliefert. (de)
- Il cheirolepide (gen. Cheirolepis) è un pesce estinto appartenente agli attinotterigi. Visse tra il Devoniano medio e l'inizio del Devoniano superiore (370 – 360 milioni di anni fa). I suoi resti sono stati ritrovati in Nordamerica (Canada e USA) e in Europa (Scozia, Spitzbergen, Bielorussia e Germania). (it)
- Cheirolepis is een geslacht van uitgestorven straalvinnige vissen die leefden in het Midden- tot Laat-Devoon. Er zijn ten minste vijf soorten benoemd. De eerste fossiele overblijfselen van dit geslacht werden gevonden in de oude rode zandsteen in Schotland, verdere fossielen komen uit Canada. Cheirolepis is de eerste bekende straalvinnige en is waarschijnlijk de primitieve zustergroep van alle andere bekende straalvinnigen. Voormalige leden van de klasse hebben alleen van het late Siluur overleefd in de vorm van individuele schubben. (nl)
- ケイロレピス (Cheirolepis) は古生代デボン紀に生息していた魚類の絶滅した属。川や湖に住み、他の魚を捕食していたと考えられている。特に頭部は口を大きく開けることができるようになっており、自分の体長の3分の2もの大きさの獲物を飲み込むことが出来た。体長約55cm。 初めての背骨を持つ生物であり、川では足りないカルシウムなどのミネラルを、この背骨から補っていた。 (ja)
- 鱈鱗魚（學名：Cheirolepis，意思為「手鰭」），又稱鰭鱗魚、手鰭魚，是已絕種的輻鰭魚，生活於泥盆紀時期的北美洲與歐洲，為一目一科一屬。鱈鱗魚為泥盆記輻鰭魚的基群，被認為是最早擁有標準型態真皮性顱骨的輻鰭魚。 鱈鱗魚體長可達55厘米（22英寸），為生活於淡水的掠食性魚類。擁有流線型的身體，體表由三角形的小盾鱗組成，與棘魚綱類似。鱈鱗魚擁有完整發展的魚鰭，提供游泳時的速度與穩定性。由眼眶的大小可知鱈鱗魚依靠視力狩獵。鱈鱗魚口中具有銳利的椎狀牙齒，並且可大幅度張口，吞噬體型達自身2/3長度的獵物。 (zh)

It is the only genus yet known within the family Cheirolepidae and the order Cheirolepiformes. It was among the most basal of the Devonian actinopterygians and is considered the first to possess the "standard" dermal cranial bones seen in later actinopterygians. Cheirolepis was a predatory freshwater and estuarine animal about 55 centimetres (22 in) long. It had a streamlined body with small, triangular ganoid scales similar to those of the Acanthodii. These scales had a basic structure typical of many early osteichthyans, with a superficial of ganoine overlying dentine, and a basal plate of bone. Cheirolepis had well-developed fins which gave it speed and stability, and was probably an active predator. Based on the size of its eyes, it hunted by sight. Cheirolepis's jaws, lined with sharp teeth, could be opened very wide, allowing it to swallow prey two thirds of its own size. (en)
