Diethylhydroxylamine (DEHA) is an organic compound with the formula (C₂H₅)₂NOH. Strictly, this is N,N-diethylhydroxylamine. It has an isomer, N,O-diethylhydroxylamine with the formula EtNHOEt. Pure N,N-diethylhydroxylamine is a colorless liquid, although it is usually encountered as a colourless-to-yellow solution in water with an amine-like odor.

DEHA can be synthesised from a reaction between triethylamine and a peroxide.
