A repulsorlift is an anti-gravity technology in the fictional Star Wars universe, capable of levitating any object to which it is applied to. It is created from constituents that are subnuclear knots of spacetime made in enormous, unmanned power refineries encompassing black holes.

Repulsorlifts are usually assembled in arrays or clusters. They may also be assembled as vanes infused with micro-coils of gravitic knots, or coils. The placement of these repulsorlifts are usually under the vehicle or spacecraft, or even a chair. Examples of hovering chairs can be seen ridden by Yoda and Cliegg Lars in Attack of the Clones.

In large ships, the repulsorlift is powered by an antigrav generator. Usually the larger the ship, the more repulsorlifts needed, and their size also increases.

Vehicles like the Death Star that moved through space only were never made to land on a surface, therefore they did not have repulsorlifts. However, smaller Death Star-like spacecraft like the Trade Federation core ships seen in Attack of the Clones had their repulsorlifts concentrated at their lower ends as they did land. In addition to the lifts, large legs and an exhaust thrust was needed to land on Geonosis as the repulsorlifts could not hold them up alone.
