A MEK inhibitor is a chemical or drug that inhibits the mitogen-activated protein kinase kinase enzymes MEK1 and/or MEK2. They can be used to affect the MAPK/ERK pathway which is often overactive in some cancers. (See MAPK/ERK pathway#Clinical significance.)

Hence MEK inhibitors have potential for treatment of some cancers,[1] especially BRAF-mutated melanoma,[2] and KRAS/BRAF mutated colorectal cancer.[3]
