The Supreme Court of Texas is the court of last resort for civil matters in the U.S. state of Texas. A different court, the Texas Court of Criminal Appeals, is the court of last resort in criminal matters. The Court has its seat at the Supreme Court Building on the State Capitol grounds in Austin, Texas.

The Texas Supreme Court consists of a Chief Justice and eight associate justices. All nine positions are elected, with a term of office of six years and no term limit.

The Texas Supreme Court was established in 1846 to replace the Supreme Court of the Republic of Texas. It meets in downtown Austin, Texas in an office building near the Texas State Capitol.
