Since the Harlem-born music icon was gunned down after a boxing match in Las Vegas in 1996, huge numbers of his fans have been convinced he did not really die and has been living a secret life.
Many who believe in the conspiracies say Tupac has been living in Cuba after faking his own death and grainy photos have previously been published on various websites claiming to show the rapper still live.
But now a video has appeared on YouTube featuring a clear photograph of a man in a red bandana and a blue jacket who bears a striking resemblance to the supposedly deceased musician.
The video asks: “Did you saw this? It is Tupac, guys, 100 per cent – same eyebrows and lips.”
Captions on the video, which has been viewed more than 1.3 million times, claim the selfie was taken in 2015 on a smartphone made in 2015 – 11 years after Tupac’s apparent death.
The coat the alleged Tupac is wearing in the photo has apparently only been available since 2014, the film’s maker claims.
Viewers then hear a tune by raper Kasinova Tha Don, who conspiracy theorists have repeatedly claimed is Tupac Shakur in disguise.
Tupac was shot in a driveway, aged 25, on September 7 1996 after watching Mike Tyson beat Bruce Seldon.
He died six days later.
Many dismissed the video as more conspiracy with one woman saying: “This look like any regular old fool with a nose ring trying to pass himself off as Tupac.”
But some appeared to believe it, with one commenter exclaiming: “He’s alive! My dad is going to be so happy!”
Earlier this year, a separate video appeared online claiming that not only was Tupac alive and living a secret life in Cuba but he was planning to make a comeback in 2016.
Kasinova Tha Don has already refuted claims he is Tupac although he has posted several cryptic messages on social media leading some to believe he is the iconic rapper, including writing: ‘2 Souls, One Body” on his Facebook page.
Express.co.uk has previously reported how a grainy black and white photograph emerged appearing to show Tupac with chart topper Rihanna. The singer was eight years old when Tupac died.
An article on American celebrity website Thereporterz.com said: “Tupac Shakur, who was supposedly killed at the age of 25, is now admitting he has been hiding this whole time.”
The author said the revelation explained why no funeral or memorial service was ever held for Tupac although he or she admitted: “It is unclear why he has been in hiding.”
Other questionable photos and videos have appeared online over the years since Tupac’s death claiming to show him alive and well but fans are still waiting for the big comeback.
