Ipso facto is a Latin phrase, directly translated as "by the fact itself", which means that a certain phenomenon is a direct consequence, a resultant effect, of the action in question, instead of being brought about by a previous action. It is a term of art used in philosophy, law, and science. An example in law is money laundering: the act is not ipso facto illegal because it is an exchange but is done as a cover for something else, so the act puts the actions of an individual in question. A common English idiom with a similar meaning is "". Compare also "by itself" and "".

Ipso Facto is a studio album by the Canadian rock guitarist Rik Emmett, released in 1992. It was Emmett's second solo studio album.
