Ljudski muskarinski acetilholinski receptor M5, kodiran CHRM5 genom, je član superfamilije integralnih membranskih proteina G protein spregnutih receptora. Vezivanje endogenog liganda acetilholina za M5 receptor postiče brojne ćelijske odgovore kao što je inhibicija adenilat ciklaze, degradacija fosfoinozitida, i modulacija kalijumskog kanala. Muskarinski receptori posreduju mnoge efekte acetilholina u centralnom i perifernom nervnom sistemu. Kliničke implikacije ovog receptora nisu potpuno istražene. Poznato je da stimulacija ovog receptora efektivno snižava nivoe cikličnog AMP-a i umanjuje aktivnost proteinske kinaze A (PKA).
