Progressive country is a term used variously to describe a movement, radio format or subgenre of country music which developed in the late 1960s and early 1970s as a reaction against the slick, pop-oriented Nashville sound. Progressive country artists drew from Bakersfield and classic honky-tonk country and rock and roll, as well as folk, bluegrass, blues and Southern rock. Progressive country is sometimes conflated with outlaw country, which some country fans consider to be a harder-edged variant, and alternative country.

Outlaw country is a subgenre of American country music created by a small group of iconoclastic artists active in the 1970s and early 1980s, known collectively as the outlaw movement, who fought for and won their creative freedom outside of the Nashville establishment that dictated the sound of most country music of the era. Willie Nelson, Waylon Jennings, Merle Haggard, Johnny Cash, Kris Kristofferson, and David Allan Coe were among the movement's most commercially successful members.
