Chenodeoxycholoyltaurine hydrolase () is an enzyme characterised from Bacteroides vulgatus that catalyzes the hydrolysis of the bile acid, taurochenodeoxycholic acid to chenodeoxycholic acid and taurine:

This enzyme is a hydrolase, one acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is chenodeoxycholoyltaurine amidohydrolase.
