}}

Habronematoidea is a superfamily of spirurian nematodes in the large order Spirurida. Like all nematodes, they have neither a circulatory nor a respiratory system.

Though none of the families placed here are overly diverse, they are quite large except for the monotypic Hedruridae. Consequently, the Habronematoidea are at present the second-largest superfamily of Spirurida, after the Filarioidea which contains the massively speciose Onchocercidae.

The families of the Habronematoidea are:

• Cystidicolidae
• Habronematidae
• Hedruridae
• Tetrameridae
