In law, a fact is a statement which is found to be true by a "tryer of fact," sometimes a jury, but often the court (the judge or judges) after hearing evidence.

Fact is to be contrasted with law. the jury is the finder of fact; the judge is the determiner of law. In the United States, appellate courts generally only consider only possible errors of law and only very rarely overturn errors of fact .

Depending on the nature of the matter the standard of proof may require that a fact be proved to be "more likely than not", that is there is barely more evidence for the fact than against; established by a preponderance of the evidence; or true beyond reasonable doubt .
