Marco Jay Luciano "Mark" Occhilupo (born 16 June 1966) is an Australian professional surfer and winner of the 1999 ASP World title.

In September 2019, he made a brief return to the international surfing circuit and took part in the So Sri Lanka Pro 2019 tournament which also marked his first visit to the country.

Over the next several years, he made a couple of half-hearted comeback attempts and remained in the public eye as a repeating star of Jack McCoy's Billabong videos.

After reaching a weight of 111-kilos, he began a training program under McCoy in Western Australia that helped him shed 34 kilos and regained his form.

He currently operates a successful podcast called the Occ-Cast which features Occhilupo talking to some of the most famous and interesting people in surfing, including Kelly Slater and Mick Fanning.
