Joe Biden’s not running for president — but the veep will be a surprise presenter at this Sunday’s Oscars, Hollywood insiders tell Page Six.

Already announced as presenting this year are Ryan Gosling, Lady Gaga, Charlize Theron, Kevin Hart, Benicio Del Toro and Whoopi Goldberg.

Michelle Obama presented Best Picture at the 2013 Academy Awards, to Ben Affleck’s “Argo,” but she appeared live via video from the White House after being introduced by Jack Nicholson.

Bill Clinton appeared at the Golden Globes the same year to introduce Steven Spielberg’s “Lincoln.”

It’s unclear what category Biden would take on. An Oscars rep didn’t immediately get back to us
