TED 2023, also known as Thus Spoke Zarathustra, The Peter Weyland Files: TED Conference, 2023 and Peter Weyland's 2023 TED Talk, is a short film based on the science fiction action media franchise Alien. Released in parts from February 28 and June 11 to October 9, 2012, as promotion for the franchise's fifth film, Prometheus, the film was directed by Luke Scott and written by Ridley Scott and Damon Lindelof, through RSA Films and 20th Century Fox. Starring Guy Pearce as Peter Weyland, the film follows the CEO as he delivers a speech about his vision for the future at the 2023 TED Conference. It streamed on YouTube on October 7, 2012.

The first short film in the Alien franchise, it received a generally positive critical reception on its initial release, and further positive appraisal in 2023 for perceived comparisons between Pearce's portrayal of Weyland and the controversies of Elon Musk.
