Newark Airport is always a zoo scene — but this is ridiculous.

A 15-inch black snake was found slithering on the floor of the New Jersey airport’s security checkpoint Monday — befuddling officials who have no idea how it got there.

“You could not make this up,” TSA spokeswoman Lisa Farbstein told The Post.

“The snake did not make it on the plane, much to the relief of whoever would have been sitting next to it,” she said.

A youngster spotted the harmless ringed-neck snake in Terminal C and a quick-thinking TSA officer trapped it with a gray checkpoint bin more accustomed to holding smelly sneakers.

The checkpoint was temporarily closed before cops came to take the animal away. It is not clear where he will end up.

Authorities will not be reviewing CCTV to reunite the snake, believed to be a lost pet, with its owner — claiming it would take too much time.

“We have a fairly robust lost and found program that reunites passengers with their lost items, but this passenger doesn’t need to call us about his snake,” TSA New Jersey Federal Security Director Tom Carter said.

Farbstein said it was up to the airline to allow pets like this on their aircraft, meaning the snake may have made it on board after all.

The strange incident comes two weeks after the Bronx Zoo lost its 3-foot venomous mangrove snake, which remains on the lam.

Zoo officials have been searching for the tree-climbing serpent since it got free from its Jungle World exhibit on Aug. 6.

Last year, another traveler at Newark made headlines when she reportedly tried to bring her emotional support peacock on a United flight to Los Angeles.
