Who is the current Chief Justice of the US Supreme Court?

John G. Roberts Jr. is the current Chief Justice of the United States Supreme Court, a position he has held since September 29, 2005. As Chief Justice, he oversees the Court's operations, presides over oral arguments, and plays a significant role in the administration of the federal judiciary. Roberts was nominated by President George W. Bush and has been influential in various landmark rulings, where he often seeks to build consensus among the justices.

The other individuals listed have held significant positions within the judiciary but are not currently serving as Chief Justice. Ruth Bader Ginsburg was a pivotal justice until her passing in September 2020, known for her advocacy for gender equality and civil rights. Clarence Thomas serves as an Associate Justice and has been on the Court since 1991, while Elena Kagan, also an Associate Justice, was appointed in 2010. Each has shaped the Court's direction in various ways, but it is Roberts who currently holds the role of Chief Justice.
