The Virginia Plan (also known as the Randolph Plan, after its sponsor, or the Large-State Plan) was a proposal to the United States Constitutional Convention for the creation of a supreme national government with three branches and a bicameral legislature. The plan was drafted by James Madison while he waited for a quorum to assemble at the Constitutional Convention of 1787.

The Virginia Plan was notable for its role in setting the overall agenda for debate in the Convention and, in particular, for setting forth the idea of population-weighted representation in the proposed national legislature. The Virginia Plan favored the interests of states with large populations, and the New Jersey Plan was proposed in response to protect small state interests.
