Bob Menendez is about to spend his “golden” years behind bars.

The disgraced New Jersey Democrat was scheduled to report at a federal prison in Pennsylvania on Tuesday to commence his 11-year sentence for a corrupt scheme that earned him the nickname “Gold Bar Bob.”

Menendez, 71, was instructed to surrender at FCI Schuykill — approximately two and a half hours’ drive from his Englewood Cliffs residence — by 2:30 p.m. after his conviction for abusing his influential Senate position to benefit personally through gold bars, cash, and other bribes.

The previously influential politician was sentenced in January, but was permitted to delay the start of his prison term after he contended he needed to support his wife, Nadine Menendez, during her trial on related bribery and corruption charges.

He’s also made a bid to score a last-minute pardon or sentence commutation from President Trump — but unless that happens Tuesday, Menendez will be calling the Keystone State prison home.

It’s likely the ex-head of the Senate Foreign Relations Committee will angle for a spot at the lockup’s minimum security camp, which allows its 225 male inmates more freedom of movement and has less staff.

FCI Schuykill also houses another 984 male inmates at a larger medium security facility.

Once inside, Menendez will be able to buy items like $8.55 Head and Shoulders shampoo, $13 Sensodyne toothpaste and $4.20 Jolly Ranchers candies from the commissary.

He’ll be able to have four visits per month and can send and receive letters and postcards, according to the prison’s website.

The crooked pol will become the lockup’s most famous inmate, though other notable residents include Gurmeet Singh Dhinsa, a former gas-station tycoon dubbed the “Gas Station Gotti” by The Post after he was convicted of ordering murders in a bid to keep secret a plot to rip off customers by tampering with pumps.

Menendez, who led the Senate committee tasked with approving massive sums of lethal military aid, was convicted by a Manhattan federal jury on July 16, 2024, of taking bribes and of serving as an illegal foreign agent for Egypt and Qatar.

He was found guilty of doling out favors to foreign governments while go-betweens showered him and his wife with cash, gold bars, a Mercedes, checks for a no-show job and payouts to a sham “consulting” firm.

FBI agents found $486,471 in cash spread out all over the Menendez couple’s house, including inside his official government jacket.

The feds also discovered 13 gold bars worth $150,000 tucked inside a safe in the couple’s bedroom.

“Somewhere along the way, you became, I’m sorry to say, a corrupt politician,” Judge Sidney Stein told the pilloried pol at his sentencing.

Nadine Menendez, 58, was also convicted of her role in the crooked scheme and is set to be sentenced in September.

She was spotted Monday getting picked up by her hubby at the Englewood Cliffs home before running an errand at what appeared to be a credit union.
