List of justices of the Supreme Court of the United States by court composition

The Supreme Court of the United States is the highest ranking judicial body in the United States. Established by Article III of the Constitution, the detailed structure of the court was laid down by the 1st United States Congress in 1789. Congress specified the Court's original and appellate jurisdiction, created 13 judicial districts, and fixed the initial size of the Supreme Court. The number of justices on the Supreme Court was changed six times before settling at the present total of nine in 1869. A total of 115 persons have served on the Supreme Court since 1789. Justices have life tenure, and so they serve until they die in office, resign or retire, or are impeached and removed from office.

The graphical timeline below lists the justices of the Supreme Court of the United States by court composition. As Supreme Court historians categorize eras in the court's history by the name of the presiding chief justice, the timeline is divided into sections, according to who was chief justice at the time. The incumbent associate justices at the start of each court era are listed in order of their seniority at that time. Justices joining the court during an era are listed below them in the order of their appointment. The bars are color-coded to show the changes in seniority among the justices during each era.
