Madonna fandom refers to the fan community of American singer-songwriter Madonna. She attained cult status amongst different audiences according to professor Sheila Jeffreys. Unlike other fandoms, her fan base does not have an official moniker, although "Madonna wannabe" became a popular media label to talk about her fans over years. The fanaticism surrounding the singer, and also called Madonnamania initiated no later than 1985. She produced consecutive successful singles in various major music markets, established numerous international records and impacted the fashion industry. Thousands of her female fans were dressing like Madonna around the world and the term "Madonna wannabe" was born. Author and scholar Lisa Lewis believes she is "one of the first women to attract the kind of devotion of young female fans normally associated with male rock stars".
Over the course of various decades, her fandom attracted diverse scholarly analyses, with her wannabes being the most studied audience at some point, flourished during the emerging of the fan studies. Her interaction with the audience has been also commented on, also as part of audience studies and media coverage. Before and after the solidification of Internet and social media, related Madonna-fan demonstrations, as well her fan clubs, fanzines, fansites, conventions and other fanatics demonstrations received significant media citations. A subject of diverse collections, Madonna topped the list "100 Most Collectable Divas" made by Record Collector in 2008. Her fandom set the world record of the biggest fan letter ever written. Madonna has also had a long list of obsessed fans and stalkers, many of whom she had personal encounters with and other of whom expressed a desire to kill her. American cult leader, David Koresh is an example. Some celebrities and other personalities, who identified publicly as her fans, were influenced by that feeling in their works, including Mexican painter Alberto Gironella, whose latest works were dedicated to or inspired by the singer.
