How many US Supreme Court justices are on the Court today?

Currently, there are nine Supreme Court justices on the United States Supreme Court. The number of justices is set by Congress and has varied from five to 10.

There have been nine justices since 1869.

In 1937, Franklin Roosevelt attempted to add six more justices to the Supreme Court. He felt the court was obstructing much of his New Deal policies and adding more members who would agree with his views would help. This was termed the "Court Packing Plan." However, Congress did not agree and so the number remains at nine.
