Cystoporida, also known as Cystoporata or cystoporates, are an extinct order of Paleozoic bryozoans in the class Stenolaemata.

[1] Their fossils are found from Ordovician to Triassic strata.

[2] All cystoporatan bryozoan genera (around 50 or so) have a "cystopore", a chamber-like supporting structure, separated from each other by transverse septa, situated between the characteristically elongated zooecia of each individual colony.
