The trailer follows the Jedi's life on Tatooine, as he protects a young Luke Skywalker from the Empire.
Ewan McGregor returns to his role as the titular Obi-Wan Kenobi, with Hayden Christensen returning as a younger Darth Vader.
The series will drop on Disney+ on May 25th - exactly 45 years after the premiere of the original Star Wars movie.
The trailer is pretty epic, with one fan commenting, "I got chills at the end of Anakin's Dark Deeds with Vader's breathing!"
While another commented, "The fact that they played duel of the fates, Anakin’s dark deeds and battle of the heroes is insane. Instant chills right there."
Have a geeze at the trailer up top.
