Anderson v. Creighton, 483 U.S. 635 (1987), is a 1987 United States Supreme Court case concerning qualified immunity.

In a 6–3 decision, the Court held that officers are entitled to qualified immunity from civil damages if they can demonstrate that a "reasonable officer" could have believed that their actions did not violate the United States Constitution, even if that belief was incorrect.

The majority opinion, written by Justice Antonin Scalia, pointed to the requirement that an official be shown to have violated "clearly established" law in order to be ineligible for qualified immunity.

Scalia's majority opinion then held that "[i]n order to conclude that the right which the official allegedly violated is "clearly established," the contours of the right must be sufficiently clear that a reasonable official would understand that what he is doing violates that right.
