In contrast to unicameralism, Multicameralism or 'polycameralism' is the condition of having multiple legislative branches of government. This can include bicameralism with two branches, tricameralism with three, tetracameralism with four branches, or a system with any amount more. The word "multicameral" can also relate in other ways to its literal meaning of "many chambered" with use in science or biology.

Many modern parliaments and congresses adopt a multicameral (usually bicameral) structure (among the best-known being the Parliament of the United Kingdom and the United States Congress) to provide multiple perspectives and a form of separation of powers within the legislature.
