What is the name of Luke’s aunt?

The story behind the answer

Luke’s aunt is Owen Lars’s wife, Beru, the moisture farmer on Tatooine who helped raise Luke from infancy. To separate the distractors: Owen Lars is the uncle; Cliegg Lars is Owen’s father (and Shmi’s husband); Shmi Skywalker is Anakin’s mother—Luke’s grandmother, not his aunt.

Beru appears in A New Hope at the Lars homestead (notably serving blue milk) and is portrayed as warm and pragmatic, urging Luke to pursue his own path. A younger version appears in Attack of the Clones when Anakin visits the Lars family. Her role grounds Luke’s humble beginnings and contrasts with the galactic-scale conflict, underscoring the franchise’s theme that extraordinary heroes can arise from ordinary lives.
