History & Origin

Mylie is one of several spellings of Miley, a name with a uniquely modern origin story: it entered the naming pool almost entirely through Miley Cyrus, whose stage name began as the family nickname Smiley. When Hannah Montana premiered in 2006, the name leapt onto U.S. birth certificates in every imaginable spelling — Miley, Mylee, Mylie, Myleigh.

Spellings with y, like Mylie, gave the celebrity-driven name a more individual look while keeping the bright sound that parents loved. All forms cooled after the initial surge, leaving Mylie a rare choice with unmistakable 2000s pop-culture roots.

Did you know? Miley Cyrus was born Destiny Hope Cyrus; her father Billy Ray called the grinning toddler 'Smiley', which shrank to Miley and eventually became her legal name.
