Miley carries 14,797 cumulative American girls on SSA record and currently sits at rank 387, with a 2008 peak. The chart traces an unmistakable single-celebrity arc: essentially zero pre-2006 presence, sharp single-year spike in 2007, peak in 2008, and a gradual decline that has now stabilized as Miley Cyrus has matured into an ongoing chart-and-cultural fixture.
The American English source
Miley originated as a nickname rather than an inherited European name. Singer Miley Cyrus, born Destiny Hope Cyrus in 1992, was given the nickname "Smiley" by her father (country star Billy Ray Cyrus) for her cheerful disposition, which was shortened to Miley. She legally changed her name to Miley Ray Cyrus in 2008, which is exactly the year of the SSA peak.
The name has essentially no significant pre-2006 American or English-language history, which puts it firmly in the constructed-celebrity-baby category alongside Khaleesi (from Game of Thrones) and other names that emerged directly from a single cultural moment. Some sources suggest Miley may have minor pre-existing use as a Welsh-derived surname, but the post-2006 SSA spike is decisively driven by the Disney Channel star.
The Disney Channel ripple
Miley sits inside a small cluster of girl names that emerged from late-2000s Disney Channel programming: Hannah, Lilly, and others all gained ground during the Hannah Montana era (2006-2011). Miley specifically tracked the show's title star and is now the most clearly identifiable celebrity-driven name of the late-2000s cohort.

The counter-reading
The single-celebrity register is the practical issue. Miley is permanently and inseparably associated with Miley Cyrus's career, which has spanned Disney Channel innocence, the controversial Bangerz era, the country revival of Younger Now, and the rock-pivot Plastic Hearts and Endless Summer Vacation. Parents choosing Miley accept that the bearer's name will be associated with whatever phase Miley Cyrus is currently in, and that the name has limited cultural anchoring outside her career.
The two-syllable MY-lee rhythm is bright and modern. Miles, Mi, and Mimi are the rare available shorter forms, though Miley tends to be used in full like most celebrity-derived names.
Sibling pairings work across the modern celebrity-coded cluster: Miley and Hannah, Miley and Selena, Miley and Demi, Miley and Ariana. Middle names tend traditional or longer to balance the casual first: Miley Rose, Miley Grace, Miley Marie, Miley Catherine. See related declining picks on the falling names list.
