List of chordate orders

This article contains a list of all of the classes and orders that are located in the Phylum Chordata.

The subphyla Tunicata and Vertebrata are in the unranked Olfactores clade, while the subphylum Cephalochordata is not. Animals in Olfactores are characterized as having a more advanced olfactory system than animals not in it.

The only extinct classes shown are Placodermi and Acanthodii. Many other extinct chordate groups are not shown here.
