Diego is the recording name of Swiss techno DJ and producer Diego Hostettler, from Bern, Switzerland. He works in techno and is associated with the Kanzleramt label.

The name is shared by several different acts, including a German indie/pop band from Karlsruhe, a Slovak group, a Slovenian punk band, a Bristol indie rock band, a Polish rapper, and others. The Swiss Diego entry refers to Hostettler rather than those other projects.
