Rock violin is rock music that includes violin in its instrumental lineup. This includes rock music only and does not include classical style music using melodic motifs from rock.

American fiddle-playing began with the early European settlers, who found that the small viol family of instruments were more portable and rugged than other instruments of the period. According to Ron Yule, "John Utie, a 1620 immigrant, settled in the North and is credited as being the first known fiddler on American soil". Early influences were Irish, Scottish, and English fiddle styles, as well as the more upper-class traditions of classical violin playing. Popular tunes included "Soldier's Joy", for which Robert Burns wrote lyrics, and other tunes such as "Flowers of Edinburgh" and "Tamlin," which have both been claimed by both Scottish and Irish lineages.
