Braun GmbH (/braʊn/ ^ⓘ "brown", German: [bʁaʊn] ^ⓘ) is a German consumer products company founded in 1921 and based in Kronberg im Taunus, Hesse. The company is known for its design aesthetic from the 1960s through the 1980s. It has manufactured a wide assortment of products ranging from electric shavers and personal care devices to radiograms and record players, movie cameras, slide projectors, clocks, and small kitchen appliances, for which "Braun became shorthand for reliable, no-nonsense modernist goods."

In 1921, Max Braun [de] (1890–1951), a mechanical engineer, established a small engineering shop in Frankfurt, Germany. In 1923, he began producing components for radio sets. By 1928, the growing company moved to new premises on Idsteiner Strasse.

In 1929, eight years after he started his shop, Max Braun began to manufacture entire radio sets, and his company eventually became one of Germany's leading radio manufacturers. This development continued with the launch of one of the first combined radio and record players, called radiograms, in 1932.

In 1935, the Braun brand was introduced, and the original incarnation of the logotype with the raised "A" was born. At the 1937 World's Fair in Paris, Max Braun received the award For special achievements in phonography. In support of the war effort during World War II, Braun discontinued making products for the civilian sector. In 1944, the Frankfurt factories were almost destroyed, and Max Braun began to rebuild his company.

After the war, Braun continued to produce state-of-the-art radios and audio equipment, and the company soon became well known for its "high-fidelity" audio and record players, including the famous SK line. Braun was the only foreign licensee of the QUAD electrostatic loudspeaker for a time. In 1954, the company also began producing film slide projectors, a mainstay of its business for the next forty years. By 1956, the company was marketing the first fully automatic tray film slide projector known as the PA 1.

The 1950s also marked the beginning of the product that Braun is known for today: the electric shaver. Braun's first electric shaver, known as the S 50, was designed in 1938, but World War II delayed its introduction until 1951. It featured an oscillating cutter block with a very thin, yet very stable steel-foil mounted above it.

The 1950s also saw the start of kitchen appliances, like the mixer MX 3 and the kitchen machine (Küchenmaschine or kitchen machine) Braun KM 3. The KM 3 is a family of food processors that started with the model KM 3/31 in 1957. Designed by Gerd A. Müller, these machines were built in nearly unchanged form for 36 years until 1993.

In 1962, Braun became Braun AG, a publicly traded company. In 1963, the company started distributing microphones by U.S. manufacturer Shure in Germany. Also during the 1960s, Braun created the Rams-designed T3 pocket radio. By this time, Braun's film slide projectors were featuring high-quality optics and all-metal construction combined with sleek functionalist styling, and competed with higher-end Eastman Kodak and Leitz products in the global market. Braun also started distributing in Germany high-end medium-format SLR system cameras produced by Japanese camera manufacturer Zenza Bronica, as well as Braun-Nizo brand cameras and Super 8 film cameras (formerly of Niezoldi & Krämer GmbH; purchased by Braun in 1962). In 1967, the Boston, Massachusetts-based conglomerate Gillette Group acquired a majority share of the company.
