Popular Science (also known as PopSci) is an American monthly magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects. Popular Science has won over 58 awards, including the American Society of Magazine Editors awards for its journalistic excellence in both 2003 (for General Excellence) and 2004 (for Best Magazine Section).

Popular science (or pop-science) is interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad-ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages.
