p21^Cip1 (ou p21^Waf1), également connue sous le nom de cyclin-dependent kinase inhibitor 1 ou CDK-interacting protein 1 est une protéine inhibitrice des CDK. Elle est connue pour inhiber les complexes CDK2 et CDK4 et permettre ainsi l'arrêt du cycle cellulaire. La protéine p53 est notamment connue pour être un régulateur de p21.
