The Top 10 Most Challenged Books of 2025 list is available now on the ALA website.
The American Library Association condemns censorship and works to defend each person’s right to read under the First Amendment and to ensure free access to information. Every year, ALA’s Office for Intellectual Freedom (OIF) compiles a list of the Top 10 Most Challenged Books in order to inform the public about censorship in libraries and schools. The lists are based on information from confidential reports filed by library professionals and community members, as well as news stories published throughout the United States.
Because many book challenges are not reported to the ALA or covered by the press, the data compiled by ALA represent only a snapshot of censorship attempts in libraries.
The 2024 data reported to ALA’s Office for Intellectual Freedom (OIF) shows that the majority of book censorship attempts are now originating from organized movements. Pressure groups and government entities that include elected officials, board members and administrators initiated 72% of demands to censor books in school and public libraries. Parents only accounted for 16% of demands to censor books, while 5% of challenges were brought by individual library users. The 120 titles most frequently targeted for censorship during 2024 are all identified on partisan book rating sites, which provide tools for activists to demand the censorship of library books.
The most common justifications for censorship provided by complainants were false claims of illegal obscenity for minors; inclusion of LGBTQIA+ characters or themes; and covering topics of race, racism, equity, and social justice.
Since 2021, ALA has tracked a sharp spike in censorship attempts in libraries. In 2024, ALA recorded the third highest number of book challenges since tracking began in 1990: ALA documented 821 attempts to censor library books and other materials in 2024 across all library types, a decrease from 2023, when a record high 1,247 attempts were reported. ALA recorded attempts to remove 2,452 unique titles in 2024, which significantly exceeds the average of 273 unique titles that were challenged annually during 2001–2020.
