Celebrities are teaming up to beg Republicans in the Electoral College to vote against President-elect Donald Trump, pledging their “respect” for potential “heroes.”

A slew of other has-been and B- or C-list celebs have piled on, calling for 37 “conscientious Republican electors” to swing the Dec. 19 Electoral College vote away from Trump. The Republican is expected to win 306 votes — more than the 270 necessary to win — based on the results from last month’s general election.

“Republican members of the Electoral College, this message is for you,” begins a preachy Martin Sheen. “As you know, our Founding Fathers built the Electoral College to safeguard the American people from the dangers of a demagogue and to ensure that the presidency only goes to someone who is to an ’eminent degree and down with the requisite qualifications.'”

“I’m not asking you to vote for Hillary Clinton,” some in the video say — just don’t vote for Trump.

“As you know, the Constitution gives electors the right to vote for any eligible person,” a celeb in the video states.

Sheen, who played the president in the hit series “The West Wing,” whose cast campaigned for Clinton, adds: “Any eligible person — no matter which party they belong to.”

“By voting your conscience, you and other brave Republican electors can give the House of Representatives the option to select a qualified candidate for the presidency,” says Richard Schiff, who played the communications director in that show.

“What is evident is that Donald Trump lacks more than the qualifications to be president. He lacks the necessary stability and clearly the respect for the Constitution of our great nation,” say the celebs.

Sheen pledges that anyone who votes his or her way will go “down in the books as an American hero,” and others say those electors will “have my respect.”

The video, released on YouTube by Unite for America, not only features Sheen and Schiff, but also Debra Messing, James Cromwell, BD Wong, Noah Wyle, Freda Payne, Bob Odenkirk, J. Smith Cameron, Michael Urie, Moby, Mike Farrell, Loretta Swit, Christine Lahti, Steven Pasquale, Dominic Fumusa and Emily Tyra.
