Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that constitutes nearly 99% of the over 30,000 living species of fish. The vast majority of extant actinopterygian species are teleosts, and by species count they dominate the subphylum Vertebrata, comprising over 50% of all living vertebrates. They are the most abundant nektonic aquatic animals and are ubiquitous throughout freshwater, brackish and marine environments from the deep sea to subterranean waters to the highest mountain streams. Extant species can range in size from Paed

輻鰭魚又名条鳍鱼，为辐鳍鱼总纲（學名：Actinopterygii）鱼类的通称，是一类鰭呈放射狀的硬骨魚。輻鰭魚是脊椎動物中種類最多的，种数几乎占现存3万多种鱼类的99%，遍及淡水及海水環境。在不同的分类系统中，辐鳍鱼的分类层级从下纲、亚纲、纲到总纲不等。基本上，广义的辐鳍鱼（Actinopterygii）包含了腕鳍鱼，而狭义的辐鳍鱼（Actinopteri）则成为腕鳍鱼的姐妹群。
