Benzonitril adalah senyawa kimia dengan rumus C6H5CN, disingkat PhCN. Senyawa ini merupakan senyawa aromatik organik berupa cairan tak berwarna dengan bau almond manis. Senyawa ini digunakan sebagai prekursor untuk resin benzoguanamin.

Senyawa ini disiapkan dengan proses amoksidasi dari toluena, reaksi dengan amonia dan oksigen (atau udara) pada 400 sampai 450 °C.[1]

C6H5CH3 + 3/2 O2 + NH3 → C6H5CN + 3 H2O

Di laboratorium dapat dibuat dengan dehidrasi dari benzamida atau oleh Reaksi Rosenmund-von Braun menggunakan tembaga sianida atau NaCN/DMSO dan aminoguanidin bikarbonat.
