Triethylamin (TEA) ist ein basisches Lösungsmittel und ein tertiäres Amin mit der Formel N(CH2CH3)3, dessen Summenformel häufig als Et3N abgekürzt wird. Im Vergleich zum einfachsten Amin, dem Ammoniak, sind alle drei Wasserstoffatome durch Ethylgruppen ersetzt. Das macht das Molekül schwerer flüchtig und viel lipophiler (unpolarer).

Triethylamine is commonly employed in organic synthesis as a base. For example, it is commonly used as a base during the preparation of esters and amides from acyl chlorides. Such reactions lead to the production of hydrogen chloride which combines with triethylamine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. Hydrogen chloride may then evaporate from the reaction mixture, which drives the reaction. (R, R' = alkyl, aryl):
