An op-ed, short for "opposite the editorial page", is a written prose piece, typically published by a North-American newspaper or magazine, which expresses the opinion of an author usually not affiliated with the publication's editorial board. Op-eds are different from both editorials and letters to the editor. In 2021, The New York Times—the paper credited with developing and naming the modern op-ed page—announced that it was retiring the label, and would instead call submitted opinion pieces "Guest Essays." The move was a result of the transition to online publishing, where there is no concept of physically opposing (adjacent) pages.
