Der Spiegel (pronounced /deːɐ ˈʃpiːɡəl/, German for "The Mirror") is a German weekly magazine, published in Hamburg. It is one of Europe's largest weekly magazines with a circulation of more than one million per week.

The first edition of the Spiegel magazine was published in Hanover on 4 January 1947, a Saturday. Its release was initiated and sponsored by the British occupational administration and preceded by a magazine titled, Diese Woche (This Week), which had been first published in November 1946. After disagreements with the British, the magazine was handed over to Rudolf Augstein as chief editor, and was renamed Der Spiegel. From the first edition in January 1947, Augstein held the position of editor-in-chief, which he retained until his death on 7 November 2002.

After 1950, the magazine was owned by Augstein and John Jahr; Jahr's share merged with Richard Gruner in 1965 to form the publishing company Gruner + Jahr. In 1969, Augstein bought out Gruner + Jahr for DM 42 million and became the sole owner of Der Spiegel. However, in 1971 Gruner + Jahr bought back a 25% share in the magazine. In 1974, Augstein restructured the company to make the employees shareholders. All employees with more than three years seniority are offered the opportunity to become an associate and participate in the management of the company, as well as in the profits.
