List of St. Louis Cardinals no-hitters: The St. Louis Cardinals are a Major League Baseball franchise based in St. Louis Missouri.  They play in the National League Central division.  Also known in their early years as the "St. Louis Brown Stockings" (1882), "St. Louis Browns" (1883–98), and "St. Louis Perfectos" (1899), pitchers for the Cardinals have thrown 10 no-hitters in franchise history.  A no-hitter is officially recognized by Major League Baseball only “when a pitcher (or pitchers) retires each batter on the opposing team during the entire course of a game, which consists of at least nine innings”.  No-hitters of less than nine complete innings were previously recognized by the league as official; however, several rule alterations in 1991 changed the rule to its current form.  A no-hitter is rare enough that one team in Major League Baseball has never had a pitcher accomplish the feat.  A perfect game, a special subcategory of no-hitter, has yet to be thrown in Cardinals history.  As defined by Major League Baseball, “in a perfect game, no batter reaches any base during the course of the game.”
