Dimethylbenzylamine is the organic compound with the formula C₆H₅CH₂N(CH₃)₂. The molecule contains the benzyl group, C₆H₅CH₂, attached to a dimethylamino functional group. It is used as a catalyst for the formation of polyurethane foams and epoxy resins.

Like some other benzyl compounds, the molecule is undergoes directed ortho metalation with butyl lithium. Because of this reaction, many derivatives are known with the formula 2-X-C₆H₄CH₂N(CH₃)₂ (X = SR, PR₂, etc).

The amine is basic and undergoes quaternization with methyl iodide to give the ammonium salt [C₆H₅CH₂N(CH₃)₃]⁺I^-. Such salts are useful phase transfer catalysts.
