吡 （ bǐ ） 咯 （ luò ） （英語： pyrrole ） [2] 是一种含有一个氮原子和两个共轭双键的五元芳香杂环化合物，化学式为C 4 H 4 NH [3] 。吡咯为一种无色挥发性液体，暴露在空气中很容易变黑。

Pyrrole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of four carbon atoms and one nitrogen atom. The simplest member of the pyrrole family is pyrrole itself, a compound with molecular formula C4H5N.

Pyrrole inhibits benzene biodegradation strongly even at pyrrole concentrations of 100-200 ug/l(1). Degradation of pyrrole seems to be enhanced with the concomitant degradation of other compounds in an aqueous environment.
