N,N-Diethylmethylamine (diethylmethylamine, DEMA) is a tertiary amine with the formula C₅H₁₃N. N,N-Diethylmethylamine is a clear, colorless to pale yellow liquid at room temperature, and is used in various industrial and scientific applications including water desalination as well as analytical and organic chemistry.

Diethylmethylamine is an acute oral and inhalation toxin although limits determining acute and chronic toxicity have not been determined, nor have the acute or chronic effects on various organ systems. Additionally, the effects of environmental exposure or accumulation are not currently known.

DEMA can be nitrosated to its corresponding nitrosamine which may present health considerations if DEMA is used in an industrial process that involves nitrating agents at low pH or high temperatures. The nitrosamine N-nitrosodiethylamine has been found in cosmetics and is a possible product of DEMA nitrosation. However, this toxic nitrosamine has only rarely been identified in cosmetic products. There are no specific storage requirements for DEMA, other than the usual precautions for storing a flammable liquid.
