4-HO-DPT, also known as 4-hydroxy-N,N-dipropyltryptamine or as deprocin, is a psychedelic drug of the tryptamine and 4-hydroxytryptamine families related to psilocin (4-HO-DMT). It is taken orally.

The drug acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT_2A receptor. It produces psychedelic-like effects in animals. The drug is closely structurally related to other psychedelic tryptamines such as dipropyltryptamine (DPT), 5-MeO-DPT, and psilocin (4-HO-DMT), among others.

4-HO-DPT was first described in the scientific literature by David Repke and colleagues in 1977. It was encountered as a novel designer drug in 2012. A presumed prodrug, 4-AcO-DPT, is also known, and has likewise been encountered as a designer drug.
