CA-125 (cancer antigen 125 or carbohydrate antigen 125) also known as "mucin 16" or "MUC16" is a protein that in humans is encoded by the MUC16 gene.

MUC16 is a member of the mucin family glycoproteins.

CA-125 has found application as a tumor marker or biomarker that may be elevated in the blood of some patients with specific types of cancers, or other benign conditions.
