para-Bromoamphetamine (PBA), also known as 4-bromoamphetamine (4-BA), is an amphetamine derivative which acts as a serotonin-norepinephrine-dopamine releasing agent (SNDRA) and produces stimulant effects.

Another related compound is para-bromomethamphetamine (PBMA) known by the codename V-111.

[1] PBA has been found to be a monoamine oxidase A (MAO-A) inhibitor, with an IC50Tooltip half-maximal inhibitory concentration of 1,500 nM.

[2] Like most other para-substituted amphetamines, PBA can be neurotoxic and may deplete the brain of 5-hydroxyindoles for at least a week.
