N-Methylhydroxylamine or methylhydroxylamine is a hydroxylamine derivative with a methyl group replacing one of the hydrogens of the amino group.

It is an isomer of methoxyamine and aminomethanol.

It decomposes in an exothermic reaction (-63 kJ/mol) into methane and azanone unless stored as a hydrochloride salt.

The compound is commercially available as its hydrochloride salt.

This can be produced by electrochemical reduction of nitromethane in hydrochloric acid using a copper anode and a graphite cathode.
