Grundig (English: /ˈɡrʌndɪɡ, ˈɡrʊndɪɡ/ GRU(U)N-dig, Turkish pronunciation: [ˈgɾundig], German pronunciation: [ˈɡʁʊndɪç]) is a Turkish home appliances and consumer electronics brand. It is owned by Arçelik A.Ş., the white goods (major appliance) manufacturer of Turkish conglomerate Koç Holding. Originally a German consumer electronics company, Grundig GmbH was founded in 1945 by Max Grundig and was headquartered for the most part in Fürth until its insolvency in 2003.

The Grundig company helped fuel the post-war economic miracle of West Germany and it grew to become one of the leading manufacturers in the world of radio, TV, recording and other electronic equipment in the following decades. In the 1970s, Philips began acquiring Grundig's shares, leading to complete control in 1993, but Philips divested Grundig by 1998. Grundig filed for bankruptcy in April 2003 after years of losses and strong competition from cheaper Asian competitors.

Most of the former Grundig business was acquired by a Turkish-British joint venture of Beko and Alba in 2004, who relaunched the Grundig brand for consumer electronics as Grundig Intermedia GmbH, whereas Grundig's car radio division was acquired by American company Delphi Corporation. In 2007, Koç Holding (parent company of Beko) acquired full ownership of Grundig and put the brand under its home-appliances subsidiary Arcelik A.Ş. The legacy society was eventually merged with Arçelik's other brand to form Beko Germany GmbH, currently based in Eschborn near Frankfurt, which functions as the German and North European headquarters of Arçelik.

Grundig began in 1945 with the establishment of a store named Fürth, Grundig & Wurzer (Radio-Vertrieb Fürth [de]), which sold radios and was headquartered in Fürth, northern Bavaria. After the Second World War, Max Grundig recognized the need for radios in Germany, and in 1947 produced a kit, while a factory and administration centre were built at Fürth. In 1951, the first television sets were manufactured at the new facility. At the time Grundig was the largest radio manufacturer in Europe. Divisions were established in Nuremberg, Frankfurt and Karlsruhe.

In 2013, Grundig launched its home appliances (white goods) product range, becoming one of the mainstream manufacturers in Europe. Parent Arcelik A.Ş., has more than 27,000 employees worldwide. Grundig has manufacturing plants in several European cities that deliver their products to more than 65 countries around the world.

Grundig started as a typical German company in 1945. Its early notability was due to Grundig radio. Max Grundig, a radio dealer, built a machine called "Heinzelmann", which was a radio that came without thermionic valves and as a do it yourself kit to circumvent post war rules. The first of the same was named the Weltklang.

Based on the success of the Heinzelmann, Grundig opened a factory. This allowed the company to start Grundig TV. This was created for the first German television channel which started in 1952. The company then developed a portable tape recorder and The Grundig Television Receiver 210.

In 1955, the American firm of Wilcox-Gay began importing Grundig radios into the U.S., using its Majestic Radio dealer network to distribute the German company's products. The marketing of "Majestic-Grundig" radios continued until Wilcox-Gay went out of business at the end of 1961.
