Metro-Goldwyn-Mayer Studios Inc. (abbreviated as MGM or M-G-M, also known as Metro-Goldwyn-Mayer Pictures, Metro-Goldwyn-Mayer or simply Metro, and for a former interval known as Metro-Goldwyn-Mayer/United Artists) is an American media company, involved primarily in the production and distribution of feature films and television programs.

Once the largest, most glamorous, and most revered film studio, MGM was founded in 1924 when the entertainment entrepreneur Marcus Loew gained control of Metro Pictures, Goldwyn Pictures, and Louis B. Mayer Pictures. Its headquarters are in Beverly Hills, California. It is one of the world's oldest film studios.

The studio's official motto, "Ars Gratia Artis", is a Latin phrase meaning "Art for art's sake". It was chosen by Howard Dietz, the studio's chief publicist. The studio's logo is a roaring lion surrounded by a ring of film inscribed with the studio's motto. The logo, which features Leo the Lion, was created by Dietz in 1916 for Goldwyn Pictures and updated in 1924 for MGM's use. Dietz based the logo on his alma mater's mascot, the Columbia University lion. Originally silent, the sound of Leo the Lion's roar was added to films for the first time in August 1928. In the 1930's and 19440's, the studio billed itself as having "more stars than there are in heaven", a reference to the large number of A-list movie stars under contract to the company. This second motto was also coined by Dietz and was first used in 1932.
