PMA (p-methoxyamphetamine) is a synthetic phenethylamine drug, psychostimulant and hallucinogen. It is synthesized starting from anethole, the flavor compound of anise and fennel. It is classified as a Schedule I hallucinogen under the Controlled Substances Act in the United States. Internationally, PMA is a Schedule I drug under the Convention on Psychotropic Substances^*.

PMA is sometimes found in illicit street "Ecstacy" tablets, either alone or in combination with other drugs, and has been associated with numerous adverse reactions including death. Effects of PMA ingestion include many effects of the hallucinogen amphetamines including accelerated and irregular heartbeat, blurred vision, and a strong, reportedly unpleasant feeling of intoxication. There are approximately twice as many deaths caused by PMA as by MDMA, although the actual occurrence of PMA on the market is only a fraction of that of MDMA.

Two analogues of PMA are known from the street: PMMA, and 4-MTA. These are the methyl and methylthio analogues of PMA, respectively. The latter was implicated in several deaths in the late 1990s.
