The Korg MS-20 is a patchable semi-modular monophonic analog synthesizer which Korg released in 1978 and which was in production until 1983.

Although the MS-20 follows a conventional subtractive synthesis architecture with oscillators, filter, and VCA, its patch panel allows some rerouting of both audio and modulation signals, alongside an external signal processor. This flexibility led to its resurgence during the analog revival of the late 1990s.
