Social media has been flooded with theories that alleged gangbanger Kilmar Abrego Garcia is covered in MS-13 tattoos — but the reality might not be what it seems.

Speculation regarding his supposed gang-related ink went into overdrive after photos emerged online of Abrego Garcia — who was shipped off to El Salvador's notorious megaprison with other reputed gang members last month — sitting down with Democratic Sen. Chris Van Hollen in El Salvador on Thursday.

Online sleuths quickly zeroed in on several tattoos visible on the 29-year-old's fingers, alleging the images proved the Trump administration's claims that Abrego Garcia was once an active MS-13 member.

Several users pointed out what they identified as a marijuana leaf, a smiley face, cross and skull inked on the father-of-three's knuckles. Some alleged the cross and skull could be cover-up tattoos designed to mask what they described as a "1" and "3."

"This looks like the most damning evidence yet," one user speculated. "Marijuana leaf = M. Smiley face = S. Cross coverup = 1. Skull coverup = 3. MS-13."

Another chimed in: "Really looks like a 1 and a 3 on his fingers there."

An ICE source told The Post that a "13" tattoo would have been mandatory for Abrego Garcia if he became part of the notorious gang while living in the US.

However, when asked about the speculation online regarding the images inked on Abrego Garcia's hands, the source said: "I've never heard of those resemblances being made."

The source said the theories could be "legit" but the only way of knowing would likely be confirmation from informants within the notorious prison.

"The best answer would be from informants and/or members within CECOT. Once he is in there, he cannot deny affiliation," the source said.

But President Trump insisted Friday that his tattoos prove Abrego Garcia is an MS-13 member.

"This is the hand of the man that the Democrats feel should be brought back to the United States, because he is such 'a fine and innocent person,'" he wrote on Truth Social alongside a photo of the purported gang tattoos.

"They said he is not a member of MS-13, even though he's got MS-13 tattooed onto his knuckles, and two Highly Respected Courts found that he was a member of MS-13, beat up his wife, etc. I was elected to take bad people out of the United States, among other things. I must be allowed to do my job. MAKE AMERICA GREAT AGAIN!"
