Van Orden v. Perry, 545 U.S. 677 (2005), was a United States Supreme Court case involving whether a display of the Ten Commandments on a monument given to the government at the Texas State Capitol in Austin violated the Establishment Clause of the First Amendment.

In a suit brought by Thomas Van Orden of Austin, the United States Court of Appeals for the Fifth Circuit ruled in November 2003 that the displays were constitutional, on the grounds that the monument conveyed both a religious and secular message. Van Orden appealed, and in October 2004 the high court agreed to hear the case at the same time as it heard McCreary County v. ACLU of Kentucky, a similar case challenging a display of the Ten Commandments at two county courthouses in Kentucky.

The Supreme Court ruled on June 27, 2005, by a vote of 5 to 4, that the display was constitutional. The Court chose not to employ the popular Lemon test in its analysis, reasoning that the display at issue was a "passive monument." Instead, the Court looked to "the nature of the monument and ... our Nation's history." The similar case of McCreary County v. ACLU of Kentucky was handed down the same day with the opposite result (also with a 5 to 4 decision).
