Justin Heath Smith (born April 3, 1981), known professionally as Austin Wolf, is an American former gay pornographic film actor.

He then worked with Randy Blue for three years, where he made his first partner video starring pornographic actor Nicco Sky.

[9][10] He signed an exclusive contract with Falcon Entertainment in April 2015 while appearing in releases for pornographic studios Raging Stallion and Hot House.

[8] In 2012, he worked on the Broadway show Bares XXII: Happy Endings,[12][13] starring Kyle Dean Massey and Jennifer Tilly.

[14] Wolf made a profile on OnlyFans, a subscription-based platform where creators set their own rates, in April 2017, where he began uploading videos of himself having sex from when he was in his twenties.

[8] In October 2018, a preview clip from an eight-minute-long 4MyFans video of an off-duty Delta Air Lines flight attendant performing oral sex on Wolf while in uniform and in an airplane bathroom aroused controversy after being uploaded to Twitter, leading to the flight attendant's suspension due to his employee ID being visible and widespread tabloid coverage of the video.

[30] In November-December 2023, he recruited top porn stars from around the world in his inaugural Collab Week event at Almar Resort in Puerto Vallarta, Mexico.

[15] David Levesley of British GQ called Wolf "a big name in gay porn" in June 2019, while, in April 2020 JC Adams of XBIZ described him as "a veteran performer with a lauded filmography" who "cemented his stardom" by being "a dazzlingly prolific content creator".

Wolf soon sparked controversy for telling a Black commenter on Instagram, who wrote that America was about "power and exploitation", that they should move.

According to Damian Williams, the United States Attorney for the Southern District of New York, the videos included one of a 10-year-old child being raped and bound by a man, while others contained children as young as infants.
