In the United States, a Miranda warning is given to suspects before they are interviewed, reminding them that they have the right to remain silent and to refuse to provide information. Any information voluntarily provided by the suspect thereafter will be admissible in evidence against them.

In effect, it serves as a reminder of the right (guaranteed by the Fifth Amendment to the US Constitution) against compulsory self-incrimination, thus ensuring due process and a fair trial.

The name derives from a case in the Supreme Court of the United States: Miranda v Arizona, 384 U.S. 436 (1966).
