α,N,N-Trimethyltryptamine (α,N,N-TMT, α-TMT, ATMT) is a psychoactive drug of the tryptamine chemical class which acts as a psychedelic hallucinogen. It is similar in structure to the other psychedelics of the tryptamine class such as dimethyltryptamine (DMT) and α-methyltryptamine (α-MT).

α-TMT has been animal tested in comparison with α-MT, and was found to produce similar effects to α-MT but with only around half the potency. Anecdotal reports from human users suggest that it produces psychedelic effects similar to those of other tryptamine derivatives when taken orally at a dose of around 80–120 mg, however it does not appear to have been widely sold or used, and its safety profile has not been studied.
