Bicameralism (from Latin: bicameralis, from bi, "two" + camera, "chamber") is a system of legislature in which the legislative branch is divided into two separate chambers or houses. It can also refer to other systems in which two chambers share power, such as the judiciary, executive, or administrative branches.

In a bicameral legislature, the two chambers typically have different powers and responsibilities. For example, one chamber may have the power to initiate legislation, while the other has the power to approve or reject it. The two chambers may also have different constituencies, such as one chamber representing the interests of the people as a whole, while the other represents the interests of specific regions or groups.

Bicameralism is often used to ensure that the interests of all groups in a society are represented in the legislature. By dividing the legislature into two chambers, it is possible to create a system in which no single group can dominate the legislative process.
