A review is an evaluation of a publication, such as a movie, video game, musical composition, or book or a piece of hardware like a car, appliance, or computer. In addition to a critical statement, the review's author may assign the work a rating (for instance, one to five stars) to indicate its relative merit. More loosely, an author may review current events or items in the news.

A compilation of reviews may itself be called a review. The New York Review of Books, for instance, is a collection of essays on literature, culture, and current affairs. National Review, founded by William F. Buckley, Jr., is an influential conservative magazine, and Monthly Review is a long-running socialist periodical.

In terms of scientific literature, reviews is a category of scientific paper, which provides a synthesis of research on a topic at that moment in time. A compilation of these reviews forms the core content of a 'tertiary' scientific journal, with examples including Annual Reviews, the Nature Reviews series of journals and Trends.
