Oikopleuridae is a family of larvacean tunicates.

A comparatively species-rich family, it has been especially well-researched thanks to the ubiquity of Oikopleura dioica as a model species.

It comprises two subfamilies, Bathochordaeinae and Oikopleurinae, itself divided into the tribes Alabiata and Labiata.

[2] It is believed to be sister to the clade formed by the two other families (Fritillariidae and Kowalevskiidae), united by common derived characteristics lacking in Oikopleuridae.
