Leu-enkefalin je endogenni opioidni peptidni neurotransmiter koji se prirodno javlja u mozgu mnogih životinja, uključujući čoveka.^[4]^[5] On je jedna od dve forme enkefalina. Druga forma je met-enkefalin. Za tirozinski ostatak u poziciji 1 se smatra da je analogan sa 3-hidroksilnom grupom morfina.

Leu-enkefalin je peptid sa sekvencom: Tyr - Gly - Gly - Phe - Leu. On proizvodi farmakološke efekte na mi i delta opioidnim receptorima, mada ima veću potentnost na delta receptoru.
