Uncle Owen is Anakin Skywalker’s stepbrother , not his biological brother. That makes Owen Lars Luke Skywalker’s step-uncle, and he and Aunt Beru end up raising Luke on Tatooine.

How the connection works

  • Shmi Skywalker, Anakin’s mother, married Cliegg Lars.
  • Owen is Cliegg’s son from an earlier relationship.
  • That marriage makes Owen and Anakin step-siblings, which is why Owen is called “Uncle Owen” to Luke.

In plain terms

Owen is related to Anakin through marriage, not blood. So the shortest answer is: Owen is Anakin’s stepbrother and Luke’s step-uncle.
