步行机是电影星球大战中的一种武器。最早步行机AT-TE出现在星际大战二部曲：复制人全面进攻中，在随后的克隆人战争及银河内战中，各种步行机都扮演了重要角色。

Walkers are fictional vehicles from the Star Wars universe that traverse the landscape on mechanical legs. They are used by the Old Republic and the Galactic Empire for ground assault or transport. Throughout the saga, walkers have played a pivotal role in the fate of characters and the outcome of battles. Industrial Light and Magic (ILM) is responsible for their animation and design, often using models, stop-motion animation, and relevant matte paintings to depict their presence in the films.
