β-Bungarotoxin is a form of bungarotoxin that is fairly common in Krait venoms.

The target of this neurotoxin is at the presynaptic terminal, where it causes release of acetylcholine and subsequent exhaustion of acetylcholine stores in the nerve terminal, by binding to proteins, most commonly actin. There are two isoforms, β₁-bungarotoxin and β₂-bungarotoxin.

It consists of two chains.
