ACTH receptor je tip melanokortin receptora (tip 2), takođe poznat kao MC₂, koji je specifičan za ACTH.^[1]

On je rasprostranjen u zona fasciculata ljudskog adrenalnog korteksa. ACTH vezivanje za receptor stimuliše produkciju kortizola. (U kontrastu s tim, produkcija aldosterona iz zona glomerulosa je stimulisana primarno angiotenzinom II.)

ACTH receptor koristi cAMP kao sekundarni glasnik.^[2]

Mutacije ovog receptora uzrokuju glukokortikoidnu deficijenciju tipa 1, u kojoj pacijenti imaju visoke ACTH nivoe u serumu, i niske nivoe kortizola.^[3][4]
