Acetone oxime (acetoxime) is the organic compound with the formula (CH₃)₂CNOH. It is the simplest example of a ketoxime. It is a white crystalline solid that is soluble in water, ethanol, ether, chloroform, and ligroin. It is used as a reagent in organic synthesis.

Acetone oxime (acetoxime) was first prepared and named in 1882 by the German chemist Victor Meyer and his Swiss student Alois Janny.
