Sisoroidea is a superfamily of catfishes (order Siluriformes). It contains the four families Amblycipitidae, Akysidae, Sisoridae, and Erethistidae; many sources also include Aspredinidae. With Aspredinidae, this superfamily includes about 42 genera and 230 species.[1]

Sisoroidea is sister to the Loricarioidea.[1] The monophyly of this superfamily is supported by a number of morphological characters.[2] Amblycipitidae is the most basal family and is sister to the remaining families.[1] Based on morphological data, Erethistidae is the sister group to Aspredinidae, with Sisoridae being the sister group of the clade formed by these two families.[3] However, it has been proposed to move the erethistid genera back into Sisoridae.[4] Also, some authors have removed Aspredinidae from Sisoroidea, having found it to be more closely related to Doradoidea (Doradidae, Auchenipteridae, and possibly Mochokidae) with morphological and molecular evidence.[5][6]
Sisoroidea includes almost exclusively Asiatic catfish families with the exception of Aspredinidae, which is native to South America.[2]
