3-APB, also known as 3-(2-aminopropyl)benzofuran, is a drug of the benzofuran family related to α-methyltryptamine (AMT). It is an analogue of AMT in which the indole ring has been replaced with a benzofuran ring.

The properties of 3-APB do not yet appear to have been reported. However, derivatives of 3-APB have been studied and described. An example is its 5-methoxy analogue mebfap (5-MeO-3-APB; a benzofuran analogue of 5-MeO-AMT), which is known to have high affinity for the serotonin 5-HT₂ receptors. In addition, 3-APBT, the analogue of 3-APB with a sulfur atom instead of an oxygen atom, is a highly potent serotonin–norepinephrine–dopamine releasing agent (SNDRA) and serotonin receptor agonist, with psychedelic-like but not stimulant-like effects in animals.

Positional isomers of 3-APB such as 5-APB and 6-APB are monoamine releasing agents and entactogens of the amphetamine and benzofuran families. Besides 3-APBT, all of the possible positional isomers of the APBTs (i.e., 2-APBT through 7-APBT) are active as potent SNDRAs and at least some also as serotonin 5-HT₂ receptor agonists.
