The reigning queen of [[LongRunners long-running]] franchises, ''Nancy Drew'' has been around in one form or another for over eighty years.

It started as a series of young adult mystery novels, the first of which was published in 1930 by the Creator/StratemeyerSyndicate. The premise is simple enough: Nancy Drew is a young teenage girl, who alongside her friends Bess and George (and sometimes her boyfriend Ned Nickerson), solves mysteries. The original series ran from 1930 all the way to 2003, consisting of 175 books in total. A sequel series, ''Girl Detective'', was published from 2004 to 2012, before being rebooted as the ''Nancy Drew Diaries'' in 2013. Along the way, a large number of spinoff book series of varying canon status were published. Between all the different series and spinoffs, the number of books totals at over ''four hundred'', and still counting.

One of the most noteworthy traits of the original books is that the first 34 volumes were [[OrwellianRetcon rewritten in the 1960s]] to reflect changing cultural values. This has produced mixed views; on one hand, this did get rid of a lot of racist stereotypes and other ValuesDissonance issues that were in the original versions. On the other hand, the changes were also criticized for making Nancy herself less assertive, and simplifying the plots of many of the books (they were 5 chapters shorter). That being said, a large number of powerful and influential women, including politician UsefulNotes/HillaryRodhamClinton, journalist Barbara Walters, and no less than three female current and former Supreme Court Justices have mentioned not only being fans, but inspired by Nancy to enter what were considered traditionally masculine fields such as politics, journalism, and law. As a result, feminists tend to have a love/hate relationship with the franchise.

Besides the books, there have been quite a few other adaptations. In the late 1930s, there was a series of four film adaptations, which were widely criticized at the time for being campy and InNameOnly (and have mostly been forgotten since). In 2002 there was a television movie, and in 2007 there was a more tongue-in-cheek [[Film/NancyDrew film adaptation]], poking fun at the 1950s incarnation of Nancy. There were two prior television series starring Nancy; the first in the late 70s, the second a 1995 series canceled after half a season. A third series, centered around an adult Nancy as a police detective, was announced in late 2015, although ultimately never greenlit. [[VideoGame/NancyDrew A series of Nancy Drew]] point-and-click AdventureGames has been in production since 1998. More recently, a comic book series was published by Papercutz, starting in 2005. There has also been occasional lines of merchandise throughout the decades.

With the variety of media and the sheer popularity of the franchise, Nancy Drew will likely be around for decades to come.
