The High Court of Justice of Galicia (Galician: Tribunal Superior de Xustiza de Galicia, TSXG) is the highest body and last judicial instance in the Galician jurisdiction, integrating the Spanish judiciary.

Together with the Parliament of Galicia (legislative branch) and the Galician Government (executive branch), the TSXG is one of the three main institutions representing Galicia's self-government, as established and regulated by the Galician Statute of Autonomy of 1981.

The TSXG was created on 23 March 1989 with the Organic Law of Judicial Authority (Galician: Lei Orgánica do Poder Xudicial), as part of the process of devolution to Galicia from the Spanish government, started in 1979.

Candidates need to obtain a three fifths (13) supermajority of the 21 votes of the General Council of Judicial Authority (Spanish: Consejo General del Poder Judicial).

The current president of the court is the progressive magistrate Miguel Ángel Cadenas Sobreira.
