What is the name of Tesla's factory in Austin, Texas?

Tesla’s factory in Austin, Texas, is called Gigafactory Texas.

The facility is located in unincorporated Travis County, just outside Austin, and is commonly nicknamed Giga Texas or Giga Austin. Tesla selected the Austin-area site in July 2020, with construction beginning later that year. Its location is why the factory is sometimes casually described as Tesla’s Austin plant, although “Austin Assembly” and “Texas Plant” are not its canonical names.

Limited Model Y production began in 2021, and Tesla held the factory’s opening celebration, called Cyber Rodeo, on April 7, 2022. The site became an important manufacturing base for Model Y vehicles and the Cybertruck, as well as Tesla’s corporate headquarters after the company announced its move from California to Texas.

Gigafactory 5 is a legitimate alternate designation because Austin was identified as Tesla’s fifth Gigafactory. However, the formal name used for the facility is Gigafactory Texas, making it the best single answer for a quiz.
