Cytochrome P450 2C9 (abbreviated CYP2C9), a member of the cytochrome P450 mixed-function oxidase system, is involved in the metabolism of xenobiotics in the body. It is involved in the metabolism of several important groups of drugs including many non-steroidal anti-inflammatory drugs (NSAIDs) and sulfonylureas.

Genetic polymorphism exists for CYP2C9 expression, with approximately 1–3% of Caucasian populations being poor metabolisers with no CYP2C9 function.
