The Cochrane Hepato-Biliary Group (The CHBG) is one of the fifty-one non-profit and independent international research publishing groups within Cochrane (formerly The Cochrane Collaboration).

The CHBG shares the same aim as the other Cochrane groups, which is to provide reliable information to practitioners, policy and decision makers, and consumers. The CHBG strives to achieve this through production, maintenance, and dissemination of hepato-biliary systematic reviews.

The CHBG systematic reviews may be:

- Systematic reviews of healthcare interventions.
- Systematic reviews of diagnostic test accuracy (DTA).
- Overview of reviews of healthcare interventions.

The CHBG systematic reviews are preceded by a publication of a peer reviewed protocol and are published in the Cochrane Database of Systematic Reviews (CDSR) in The Cochrane Library (The CLib).

The CHBG assembles a Hepato-Biliary Controlled Trials Register. The CHBG Controlled Trials Register is published in The Cochrane Central Register of Controlled Trials (CENTRAL).

The CHBG activities follow the policy and principles of Cochrane.

Clinicians, researchers, healthcare consumers, and people with many other different proffesions contribute to the work of The CHBG from different parts of the world.
