A nyckelharpa (literally "key harp", plural nyckelharpor), sometimes called a keyed fiddle, is a traditional Swedish musical instrument. It is a string instrument or chordophone. Its keys are attached to tangents which, when a key is depressed, serve as frets to change the pitch of the string.

The nyckelharpa is similar in appearance to a fiddle or the bowed Byzantine lira. Structurally, it is more closely related to the hurdy gurdy, both employing key-actuated tangents to change the pitch. The nyckelharpa and its tonal range appear on the reverse of the Swedish 50 kronor banknote.

A depiction of two instruments, possibly but not confirmed nyckelharpor, can be found in a relief dating from circa 1350 on one of the gates of Källunge church on Gotland. Early church paintings are found in Siena, Italy, dating to 1408 and in different churches in Denmark and Sweden, such as Tolfta church, Sweden, which dates to circa 1460-1525. Other very early pictures are to be found in Hildesheim, Germany, dating to circa 1590.
