Elk was a Japanese guitar, amplifier and music-electronics brand during the 1960s and 1970s. Elk instruments were built by the Miyuki Company and were mostly distributed within Japan. Miyuki reportedly stopped making ELK amplifiers (and possibly the guitars as well) in the early 1970s and manufacture was taken over by Hoshino Gakki (the owners of the Ibanez brand).

Elk mainly exported amplifiers but a few guitar models were distributed and were reputedly of good quality. For example the Elk 1972 English language catalog only lists three guitar models: a thinline semi acoustic, a solid-body electric and a bass. The 1972 Japanese catalogue has a lot more models.
