洛卡比里（Rockabilly），是一种50年代的音乐。它是乡村音乐（例如 hillbilly）和蓝调、Boogie Woogie、 Gosbell的融合。后来猫王出道之后，洛卡比里在美国、英国、欧陆、日本等各地逐渐发展起来。大约在1954年－1958年之间，是洛卡比里的最盛期，又称之为纯洛卡比里时代（Pure Rockabilly）。

西元1980年代洛卡比里再度复活，并形成一种穿着音乐加庞克风味的衣服，例如Stray Cats 及Rockats乐团等，又称之为新洛卡比里时代（Neo rockabilly）。

Rockabilly is one of the earliest styles of rock and roll music, dating back to the early 1950s in the United States, especially the South. As a genre it blends the sound of Western musical styles such as country with that of rhythm and blues, leading to what is considered "classic" rock and roll. Some have also described it as a blend of bluegrass with rock and roll. The term "rockabilly" itself is a portmanteau of "rock" (from "rock 'n' roll") and "hillbilly", the latter a reference to the country music (often called "hillbilly music" in the 1940s and 1950s) that contributed strongly to the style. Other important influences on rockabilly include western swing, boogie woogie, jump blues, and electric blues.
