MMDA (3-methoxy-4,5-methylenedioxyamphetamine; 3-methoxy-MDA) is a psychedelic and entactogen drug of the amphetamine class. It is an analogue of lophophine, MDA, and MDMA.

MMDA was described by Alexander Shulgin in his book PiHKAL. Shulgin lists the dosage range of MMDA as 100–250 mg. The first symptoms appear within 30–60 minutes following oral administration. MMDA produces euphoria and loving warmth, and attenuates feelings such as anxiety and loneliness. MMDA also produces eyes-closed visuals, a state of drowsiness, muscle relaxation, and time dilation. Side effects include moderate mydriasis, dizziness, sensations of heat or cold, and trembling. The imagery is generally realistic, and often related to everyday perception of people, landscapes, or objects. The effects of MMDA usually reach a peak during the first hour following the initial symptoms, and begin to wane during the second hour, and usually completely disappear by the end of the fifth hour.
