A letter to the editor (sometimes abbreviated LTTE) is a letter sent to the editors of a publication or periodical about materials that have appeared in the publication or issues of concern to the readership, usually intended for publication. Letters to the editor often appear in news media, though they also appear in non-news publications, such as many magazines. In many publications, letters to the editor may be sent either through conventional mail or electronic mail.

Letters are usually short, as they must sometimes fit in a limited space. Many newspapers require that letters to the editor be under a certain number of words, and may attach other conditions, such as prohibiting anonymous letters, letters that contain misinformation or are meant to libel someone, are obscene or in poor taste, or are meant to resolve a personal conflict.

Letters to the editor are traditionally associated with newspapers and newsmagazines, though similar letters are sent to websites, radio stations, and television programs, who may read them on air. Letters may support or oppose a publication's editorial stance, remark on materials that have appeared in the publication, or correct a perceived error or misrepresentation.

They are also used in astroturfing campaigns to create the illusion of grassroots popular support in the community for a particular cause, candidate, or party.
