Weyland-Yutani is a fictional corporation in the motion picture Alien and its sequels, often referred to simply as "The Company". It is one of the corporations that runs the human colonies outside the solar system through the Extrasolar Colonization Administration, has a seat in the Interstellar Commerce Commission's Company Review Board, and also has a large presence on Earth.

Weyland-Yutani is consistently portrayed as exhibiting the worst aspects of corporate profiteering, and as being willing to sacrifice decency and human life in the pursuit of profit. In various portrayals of the Aliens' universe, the corporation has its hands in all aspects of space colonization and research. The corporation has consistently ordered its employees and agents to attempt to obtain living xenomorphs so that they can be exploited as a biological weapon, of course, without regard for their obtainers lives.

Weyland-Yutani is a modern example of the longstanding trope of the evil megacorporation in science fiction.
