Leave my Veep alone!

President-elect Donald Trump got into a Twitter duel with the cast of the mega-hit show “Hamilton” on Saturday for lecturing Vice President-elect Mike Pence and questioning whether he’ll uphold “American values.”

“Our wonderful future V.P. Mike Pence was harassed last night at the theater by the cast of Hamilton, cameras blazing,” Trump tweeted in the first of several volleys.

“This should not happen!”

In what could be a preview of the new White House’s aggressive online demeanor, the tweeter in chief blasted the Broadway musical for violating theater tradition and common courtesy in calling out his right-hand man.

Instead of pistols at dawn, Trump and the actor who plays Aaron Burr fired off opposing tweets.

“The Theater must always be a safe and special place. The cast of Hamilton was very rude last night to a very good man, Mike Pence. Apologize!” Trump wrote in his second of three tweets in defense of his No. 2 on Saturday.

Brandon Victor Dixon, who plays Burr, responded to Trump’s tweet within minutes: “Conversation is not harassment sir. And I appreciate @mike_pence for stopping to listen.”

The Twitter war went silent for the next 12 hours, as Trump and Pence busied themselves with the business of transition, holding a series of meetings with candidates for Cabinet and other positions at the president-elect’s golf club in Bedminster, NJ.

But unwilling to let go, Trump fired off the final tweet in the volley shortly after concluding the day of meetings.

“Very rude and insulting of Hamilton cast member to treat our great future V.P. Mike Pence to a theater lecture,” Trump tweeted shortly after 7:30 p.m., referring to Dixon.

“Couldn’t even memorize lines!” he added, in an apparent reference to Dixon having read his little speech from a piece of paper.

Oddly, Trump’s last tweet was taken down minutes later.

Dixon and other cast members of the Tony Award-winning show paused during Friday’s curtain call to appeal directly to the vice president-elect.

“We, sir, we are the diverse America who are alarmed and anxious that your new administration will not protect us, our planet, our children, our parents or defend us and uphold our inalienable rights, sir,” Dixon said.

“But we truly hope this show has inspired you to uphold our American values and work on behalf of all of us. ”

The public lecture was unprecedented. “They could have requested him to come backstage and express their point of view, but to call out any theater-goer while they are simply enjoying a Broadway show is inappropriate and unnecessary,” said GOP strategist Susan Del Percio.

Pence got a mix of cheers and jeers as he found his orchestra seat for the Broadway show at the Richard Rodgers Theatre.

It was a markedly different reception than the one President Obama received when he attended Lin-Manuel Miranda’s musical in July 2015. Audience members snapped photos and shouted “God bless Obama!” as he and his daughters took their seats.

In fact, it was a private performance for Obama that paved the way for “Hamilton.” Miranda performed freestyle verse about the Founding Fathers during the “White House Poetry Jam” in 2009, becoming the basis for the Broadway hit.

It is rare for a president or vice president to have an uncomfortable experience on the Great White Way. Further uptown, President Ronald Reagan and First Lady Nancy were booed as they watched the American Ballet Theater company at the Metropolitan Opera House early in Reagan’s presidency.

On Friday night, however, it was the performers who turned hecklers, treating the veep like a Burr-like pariah in the president-elect’s own hometown.

Dixon was unapologetic Saturday. He told the Web site Broadway.com that he hopes Pence, whom critics have slammed for supporting conversion therapy for gays as Indiana governor, takes the message to heart.

“I saw him enjoying it with whoever he was with, and I hope he remembers us. I truly believe we had an effect,” continued Dixon.

“It was a message from the producers, the creative [team] and the cast. If you have differences, say something! What better place than on this stage telling this story with these people? I hope he thinks of us every time he has to deal with an issue or talk about a bill or present anything.”

The cast checked in with producers and creator Miranda when they found out Pence would attend, Dixon told the Web site. But an insider said that Dixon went a bit off-script with “his own riff.”

Miranda tweeted his pride in the cast after the show Saturday.

“Proud of @HamiltonMusical. Proud of @BrandonVDixon, for leading with love. And proud to remind you that ALL are welcome at the theater,” he wrote.

Outraged conservatives launched a #BoycottHamilton hash tag and admonished the performers on Twitter Saturday.

“The arrogance and hostility of the Hamilton cast to the Vice President elect (a guest at the theater) is a reminder the left still fights,” tweeted former House Speaker Newt Gingrich.

The comments were met with sarcastic responses that noted a boycott won’t work for a show that is already sold out for months.

“You know what? I support #BoycottHamilton. I hope it intensifies — especially during the first week of March, maybe that Sunday matinee?” tweeted comedian Patton Oswalt.

Some conservative activists threatened to organize a flash- mob protest Saturday night at the theater to boo the performers before the show.

Several visitors in the theater lobby could be overheard Saturday afternoon inquiring about how to cancel their tickets and get refunds.

But it was 80 anti-Trump protesters (one inset left) who showed up outside the theater around 4 p.m. chanting, “This is what democracy looks like,” “We Love Hamilton,” and “Team Bannon go away, racist, sexist, anti-gay” a reference to Steve Bannon,

Trump’s White House chief strategist.

At least 20 cops stood watch over the peaceful protest.

A spokesman for the theater backed Dixon’s statement.
