'''''N''-Methylmorpholine''' is the organic compound with the formula O(CH<sub>2</sub>CH<sub>2</sub>)<sub>2</sub>NCH<sub>3</sub>. It is a colorless liquid. It is a cyclic tertiary amine. It is used as a base catalyst for generation of polyurethanes and other reactions. It is produced by the reaction of methylamine and diethylene glycol as well as by the hydrogenolysis of N-formylmorpholine.<ref name=Ullmann>{{cite encyclopedia|author=Karsten Eller |author2=Erhard Henkes |author3=Roland Rossbacher |author4=Hartmut Höke |title=Amines, Aliphatic|encyclopedia=Ullmann's Encyclopedia of Industrial Chemistry|year=2005|publisher=Wiley-VCH|location=Weinheim|doi=10.1002/14356007.a02_001|isbn=3-527-30673-0}}</ref> It is the precursor to ''N''-methylmorpholine ''N''-oxide, a commercially important oxidant.
