In Doctor Who, what is the name of the 2010 episode in which the Doctor finds the Pandorica?

The Doctor Who episode in which the Doctor finds the Pandorica is titled “The Pandorica Opens.”

“The Pandorica Opens” is the first part of the fifth series finale of Doctor Who. It was written by Steven Moffat and first broadcast in 2010. The episode follows the Eleventh Doctor, played by Matt Smith, as he investigates a mysterious object beneath Stonehenge.

The Pandorica is presented as an ancient prison containing an unknown captive. The Doctor believes it may hold the greatest threat in the universe, but the episode’s revelations turn the situation into a trap involving many of his enemies.

The title intentionally echoes Pandora’s box while using “Pandorica,” a fictional name suited to Doctor Who’s mythology. It is often confused with “The Big Bang,” the following episode, which concludes the two-part finale. “The Eleventh Hour” is the opening episode of Smith’s era, not the Pandorica story.
