Pringles Unsung was a music competition in the United Kingdom that ran once from 2006 to 2007.
 It was sponsored by the Pringles snack brand, and was one of several brand-sponsored music competitions to be launched during this period.
 The competition invited unsigned artists to upload a song to the official Pringles Unsung website, where they could then be voted on by the general public and a panel of judges.
 The most popular songs from each of seven regions progressed to regional heats in Newcastle upon Tyne, Birmingham, Ipswich, Kingston upon Thames, Leeds, Bristol and Plymouth.
 The winners of the regional heats then competed in a grand final, where they each performed in front of the judging panel.
 The judging panel consisted of producers Kevin Bacon and Jonathan Quarmby, ex-Island Records managing director Marc Marot, journalist Paul Sexton and Echo & the Bunnymen lead singer Ian McCulloch.
 McCulloch had become involved as he wanted to encourage exciting new music.
