4-HO-MPT, also known as 4-hydroxy-N-methyl-N-propyltryptamine or as meprocin, is a psychedelic drug of the tryptamine and 4-hydroxytryptamine families. It is a higher homologue of psilocin (4-HO-DMT) as well as the 4-hydroxyl analogue of N-methyl-N-propyltryptamine (MPT). The drug is taken orally.

It acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT_2A receptor. The drug produces psychedelic-like effects in animals.

4-HO-MPT was first described in the scientific literature by 1981. It was encountered as a novel designer drug by 2021.
