Potassium channel subfamily K member 9 is a protein that in humans is encoded by the KCNK9 gene.

This gene encodes K_2P9.1, one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. This open channel is highly expressed in the cerebellum. It is inhibited by extracellular acidification and arachidonic acid, and strongly inhibited by phorbol 12-myristate 13-acetate. Phorbol 12-myristate 13-acetate is also known as 12-O-tetradecanoylphorbol-13-acetate (TPA).
