Journal of the Renin-Angiotensin-Aldosterone System (JRAAS) is a peer-reviewed journal published quarterly as a resource for biomedical professionals, including basic scientists and clinicians, primarily with an active interest in the renin-angiotensin-aldosterone system in humans and other mammals.

It publishes original research articles and reviews on the normal and abnormal function of this system and its pharmacology and therapeutics, mostly in a cardiovascular context but including research in all areas where this system is present, including the brain, lungs and gastro-intestinal tract.

Although this is its main focus, JRAAS also publishes research on other peptides, such as vasopressin, the natriuretic peptides and the kallikrein-kinin system.
