The Radiators, also known as The New Orleans Radiators, were a rock band from New Orleans, Louisiana, who combined the traditional musical styles of their native city with more mainstream rock and R&B influences to form a bouncy, funky variety of swamp-rock they called fish-head music. Described by OffBeat magazine as "New Orleans' longest-running and most successful rock band", The Radiators' had only limited commercial success, with only a handful of chart appearances, but, as a party band from a party town, their enthusiastic live performances, danceable beats and relentless touring earned the band a dedicated following and the admiration of many of their peers. In a feat of continuity rarely seen in the rock music world, the five-man line up in the year of their breakup (2011) is the same one as when the band formed in 1978.

The Radiators had a repertoire which included over three hundred original songs—many never released on album—and over one thousand covers (or partial covers used as part of a medley). With the band's approval, over 500 concert recordings have been made available for free (for non-commercial use) on the Internet Archive.
