o-Nitroanisole is an organic compound with the formula CH₃OC₆H₄NO₂. Three isomers of nitroanisole exist, but the o-isomer is the most commercially important. It is a colorless liquid.

It is prepared by treatment of o-chloronitrobenzene with sodium methoxide:^[1]

NaOCH₃ + ClC₆H₄NO₂ → CH₃OC₆H₄NO₂ + NaCl

The resulting 2-chloronitrobenzene can be reduced to o-anisidine, which is a precursor to dyes.
