The YK-20 is a music keyboard released by Yamaha. It has 48 keys and is classified as a full-sized keyboard with a sheet music stand. It is meant to be used with either the SFG-01 or SFG-05 FM Sound Synthesizer unit.

It uses the same 20-pin IDC connector and is interchangeable with the Panasonic FS-MKB1, Toshiba HX-MU901, Yamaha YK-01 and YK-10 music keyboards.

The same 20-pin connector is also used on the Philips NMS 1160 music keyboard, but the pinout is different.
