苯并芘（英语：Benzopyrene）是苯与芘稠合而成的一类多环芳烃。根据稠合的位置不同，可以有苯并[a]芘和苯并[e]芘两种异构体，这两个名称来源于IUPAC命名法中对芘分子环中各化学键的编号（见右图）。
最常见的苯并芘是苯并[a]芘。它是一种致癌物质和突变原。

A benzopyrene is an organic compound with the formula C20H12. Structurally speaking, the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene group. Two isomeric species of benzopyrene are benzo[a]pyrene and the less common benzo[e]pyrene. They belong to the chemical class of polycyclic aromatic hydrocarbons.
