Nephrozoa is a proposed major cladeofbilaterian animals. It includes all bilaterians other than Xenacoelomorpha. It contrasts with the Xenambulacraria hypothesis, which instead posits that Xenacoelomorpha is most closely related to Ambulacraria.^{[1][2][3][4][5]} Which hypothesis is correct is controversial. Authors supporting the Xenambulacraria hypothesis have suggested that the genetic evidence used to support Nephrozoa may be due to systematic error.^[1]

Below is a proposed phylogenetic tree of Nephrozoa:
