N-Methylethanolamine is an alkanolamine with the formula CH₃NHCH₂CH₂OH. It is flammable, corrosive, colorless, viscous liquid. It is an intermediate in the biosynthesis of choline.

With both an amine and a hydroxyl functional groups, it is a useful intermediate in the chemical synthesis of various products including polymers and pharmaceuticals. It is also used as a solvent, for example in the processing of natural gas, where it is used together with its analogs ethanolamine and dimethylethanolamine.
