鼠鱚目为辐鳍鱼纲的一目。其下分成3个亚目：

• 虱目鱼亚目(Chanoidei)
• 鼠鱚亚目(Gonorynchoidei)
• 尼罗鱼亚目(Knerioidei)

The Gonorynchiformes are an order of ray-finned fish that includes the important food source, the milkfish (Chanos chanos, family Chanidae), and a number of lesser-known types, both marine and freshwater.

The alternate spelling "Gonorhynchiformes", with an "h", is frequently seen but not official.
