Darold Ferguson, Jr. (born October 20, 1988), better known by his stage name ASAP Ferg (stylized as A$AP Ferg), is an American hip hop recording artist from New York City's Harlem neighborhood. Aside from his solo career, he is a member of the hip hop collective A$AP Mob, from which he adopted his moniker. In January 2013, Ferg signed a solo record deal with Polo Grounds and RCA, the same labels that helped launch A$AP Worldwide, when Ferg's A$AP Mob cohorts A$AP Rocky and the late A$AP Yams, negotiated their own respective deal in 2011. His debut album Trap Lord was released on August 20, 2013, and was met with generally positive reviews. On April 22, 2016, Ferg released his second studio album, Always Strive and Prosper.

Ferg was raised in an area notoriously known as "Hungry Ham (Hamilton Heights)". His father (Darold Ferguson) owned a Harlem boutique and printed shirts and logos for record labels; including Bad Boy Records and luminaries such as Teddy Riley, Heavy D, Bell Biv DeVoe, and more. Even though he immersed himself in music, the younger Ferg pursued fashion at first. Inspired by his father, who died of kidney failure, Ferg launched clothing and jewelry lines at a young age and attended art school. In 2005, Ferg began launching the "Devoni Clothing", that he designed and distributed high-end belts, which have been worn by Chris Brown, Swizz Beatz and Diggy Simmons.
