The chief justice of the Supreme Court of Tasmania is the senior judge of the Supreme Court of Tasmania, and the highest ranking judicial officer in the Australian state of Tasmania.

The chief justice is both the judicial head of the Supreme Court as well as the administrative head, responsible for arranging the business of the court and establishing its rules and procedures.

The current chief justice is Chris Shanahan, whose appointment was announced in 2024 by the Tasmanian Attorney-General.

Due to an age limit changed at the request of Chief Justice Blow, the incumbent chief justice must retire upon reaching the age of 75.

The chief justice also holds the role of lieutenant governor of Tasmania.
