A four-stringed musical instrument with a small banjo-type body and a fretted ukulele neck.

An early complaint levelled at the ukulele was insufficient volume. Alvin D. Keech produced the first banjulele, a combination of the American banjo and the Hawaiian ukulele, around 1920 and patented the name. From then on, other instrument makers made banjuleles (or banjoleles) but were unable to call their instruments by those names so they were called banjo ukulele or ukulele banjo instead.

The banjolele was the instrument played by British comedian George Formby (1904–1961), who developed his own style of playing in accompaniment to his comic songs. His name is associated with the instrument more than that of any other musician.
