Dopaminski receptor D4 je G protein spregnuti receptor kodiran DRD4 genom.[1] Poput drugih dopaminskih receptora, D4 receptor se aktivira neurotransmiterom dopaminom. On je povezan sa mnogim neurološkim i psihijatrijskim oboljenjima, neka od kojih su šizofrenija, Parkinsonova bolest, bipolarni poremećaj, adikcije, i poremećaji ishrane kao što su anoreksija nervoza, bulimija nervoza i nekontrolisano jedenje.

D4 je biološka meta za lekove kojima se tretira šizofrenija i Parkinsonova bolest. Ovaj receptor je sličan sa D2 receptorom, u smislu da aktivirani receptor inhibira enzim adenilat cilazu, čime se redukuje intraćelijska koncentracija sekundarnog glasnika cikličnog AMP-a.[2]
