"Get Rhythm" is a song written and recorded by American singer-songwriter and musician Johnny Cash. It was originally released as the B-side to the single release "I Walk the Line" in 1956 on Sun 241. It was re-released with overdubbed "live" effects in September 1969 as an A-side single and reached number 60 on the Billboard Pop chart.

The song is about optimism, centering on a shoeshine boy who "gets rhythm" to cope with the tedious nature of his job.

Alice Randall in the book "My Country Roots: The Ultimate MP3 Guide to America's Original Outsider Music" asks the question, "racist, racialist, or race appreciating? You decide. Maybe the grinning "boy" hides something worth knowing in his mask as well as behind his mask."

"Get Rhythm" was released in 1956 as the B-side to Cash's first Number One hit, "I Walk the Line." In 1969, the original recording of "Get Rhythm" was released as a single itself, with sound effects dubbed in to simulate the sound of a live recording. This rerelease went to #23 on the country charts.

In 1991, Martin Delray recorded a cover of the song on his debut album, also entitled Get Rhythm. Released as his debut single, Delray's version featured guest vocals from Cash, as well as a guest appearance by him in the music video. It peaked at #27 on the country charts.
