Most of the claims of people spotting the star, or him being pictured, have turned out to be doctored photos or lookalikes - but now a YouTube video has emerged that claims to PROVE Tupac has been with us all along.
The video, which has more than 1.3 million views, includes a selfie of a man wearing an bandanna who bears an uncanny resemblance to the fallen hip hop star.
It is claimed the man is "Tupac guys 100% same eyebrows and lips".
The subtitles in the video state the photo is a "selfie" taken in 2015 on a phone "made in 2011" – 11 years after his death.
It does not say where the selfie was sourced.
The video then plays out a song by rapper Kasinova Tha Don, who suspiciously "sounds exactly like Tupac Shakur".
Kasinova Tha Don has repeatedly refuted claims he is Tupac.
However, according to Hubpages.com, he has dropped multiple hints on his Facebook page, including the cryptic comment: "2 Souls, One Body"
The YouTube channel behind the video, Tupac Legacy, does stress it is "not 100% he is alive but I want to share my view".
Last year, a retired police officer claimed he was paid $1.5million to help the star fake his own death .
David Myers, who was on his deathbed at the time, said: "The world needs to know what I did. I'm ashamed that I let a price be put on my word and I cannot die without letting the world know.”
Over 30 people were reportedly paid to help fake his death – including police, medics and various witnesses.
Myers even claims 2Pac paid $50,000 for a body double to be taken to the morgue.
On September 7, 1996, Tupac was shot multiple times in a drive-by shooting at the intersection of Flamingo Road and Koval Lane in Las Vegas, Nevada.
He had been at the Mike Tyson vs Bruce Sheldon boxing match and been involved in a altercation with gang member Orlando "Baby Lane" Anderson.
A short while later, while en route to a night club, a car pulled up alongside Shakur's while he was standing with his head out of the sunroof and unknown occupants shot him, hitting him in the chest, pelvis, right hand, thigh and lung.
To this day, police still have no idea who killed the star.
