US authorities want to make sure the third time’s not the charm.

El Chapo, who has previously escaped Mexican prisons — twice — will likely be sent to “The Alcatraz of the Rockies,” or ADX Florence, the US’ only supermax prison, to do his time.

But the top-security Colorado digs will still be a relative cakewalk compared to what Joaquin “El Chapo” Guzman has been enduring, his lawyers say.

“Wherever he’s going is better than where he is now,” said Chapo lawyer Jeffrey Lichtman on Tuesday, hours after a Brooklyn federal jury found the short-fry former head of the world’s most powerful narcotics cartel guilty of on all counts at his narcotics trafficking trial.

The 61-year-old drug lord has been in solitary confinement in the Metropolitan Correctional Center in Manhattan for the past two years.

“The light is always on. He has absolutely no view to the outside and no contact with any other inmates,’’ said another Chapo lawyer, William Purpura. “He’s not getting fresh air.”

At Florence, at least he’d have access to the “dog run” for up to two hours a day, Purpura said.

“He will eventually … work himself into less restrictive conditions,” the lawyer added. “I can tell you, the location, even though it’s maximum security, he’ll have more liberty there.”

The convicted kingpin faces life in prison when sentenced June 25. The US Bureau of Prisons will decide where he’ll do his time.

Security is sure to be the top consideration for authorities, given Chapo’s slippery past.

He previously escaped from one Mexican prison hidden in a laundry cart and another through a tunnel.

But the inmates at ADX Florence — who have included everyone from 9/11 conspirator Zacarias Moussaoui to Unibomber Ted Kaczynski and Mafioso Vincent “Vinnie Gorgeous” Basciano — might beg to differ that they have anything close to easy.

“It ain’t no lollygagging solitary confinement like you have at some other prisons — it’s 22, 23 hours in this concrete room, then one [to two] hours in this fenced-in area,” although “sometimes they just canceled [the outside privilege] for no reason,’’ ex-inmate Travis Dusenbury told The Marshall Project in 2016.
