Etching may refer to:
* Etching, a printmaking technique in art
* Etching (glass), a glass decoration technique
* Etching (metal), a metal decoration technique
* Industrial etching
* Etching (microfabrication), a process in producing microelectronics Note that all of the above can be called chemical etching, though the term is mostly used for industrial etching. An etcher is most likely to mean a printmaker. An etchant (sometimes mordant) is any chemical used to etch, but probably refers to an industrial process.
