Destiny Hope Cyrus was born on November 23, 1992, in Nashville, Tennessee, to Letitia Jean "Tish" (née Finley) and country singer Billy Ray Cyrus. Her name was derived from her parents' belief that she would accomplish great things with her life, and was given the nickname "Smiley", later shortened to "Miley", because she often smiled as an infant.

Against the advice of her father's record company, Cyrus's parents secretly married a month after Cyrus's birth on December 28, 1992.
