David Archuleta was born in Miami, Florida, to Jeff Archuleta and Lupe Marie, a salsa singer and dancer from Honduras. Archuleta has four siblings. Archuleta's family moved to the Salt Lake Valley, to the city of Sandy, Utah, when Archuleta was six. He currently lives in Murray, Utah, where he is a student at Murray High School.

Archuleta started singing at age six, inspired by a Les Misérables video. "That musical is what started all of this," he said. He started performing publicly at age 10 when he participated in the Utah Talent Competition singing "I Will Always Love You" by Dolly Parton; he received a standing ovation and won the Child Division.

Archuleta was inspired by watching both Tamyra Gray and Kelly Clarkson to "see what performing and really getting into a song was like" during the beginning weeks of the premiere season of American Idol. He later made his television debut, at eleven years old, singing "And I Am Telling You I'm Not Going" on a Jenny Jones
