In the long history of the Billboard 200 (or its historical antecedents -- Billboard album charts date back to the '40s in one form or another), there have been surprisingly few solo artists to top the album chart under the age of 18. In fact, even going as far back as the '40s, just 11 solo artists have topped Billboard's primary album chart. To be clear, we're not including people who were in a band or duo that scored a No. 1 album -- nor are we including minors who contributed to No. 1 soundtracks.

From Billie Eilish to Shawn Mendes to '50s teen idol Ricky Nelson, here are 11 solo singers who topped the album chart before turning 18.
