Ethylpropyltryptamine (EPT), also known as N-ethyl-N-propyltryptamine, is a rarely encountered psychedelic drug in the tryptamine family. It has been identified in illicit products in Japan.

EPT was not included nor mentioned in Alexander Shulgin's book TiHKAL (Tryptamines I Have Known and Loved).

Analogues of EPT include methylethyltryptamine (MET), methylpropyltryptamine (MPT), diethyltryptamine (DET), dipropyltryptamine (DPT), among others.

EPT is not a controlled substance in Canada as of 2025.

It is illegal to sell, distribute, supply, transport or trade the pharmaceutical drug under the Psychoactive Substances Act of 2016.

EPT is unscheduled but it may be considered an analogue of DMT, which is a Schedule I drug under the Controlled Substances Act. As such, the sale for human consumption could be illegal under the Federal Analogue Act.
