The Connecticut Compromise (also known as the Great Compromise of 1787 or Sherman Compromise) is an agreement that both large and small states reached during the Constitutional Convention of 1787 that in part defines the legislative structure and representation that each state will have under the United States Constitution.

It retains the bicameral legislature as proposed by Roger Sherman, along with proportional representation of the states in the lower house, but requires the upper house to be weighted equally between the states.

Each state will have two representatives in the upper house.
