C. Bechstein GmbH (also known as Bechstein, German pronunciation: [ˈbɛçʃtaɪn]) is a German piano manufacturer of grand and upright pianos, established in Berlin in 1853 by piano builder Carl Bechstein.

Young Carl Bechstein studied and worked in France and England as a piano craftsman, before he became an independent piano maker. His first pianos were made for other companies.

C. Bechstein piano factory was founded on 1 October 1853 by Carl Bechstein in Berlin, Germany.

Carl Bechstein set out to manufacture a piano able to withstand the great demands imposed on the instrument by the virtuosi of the time, such as Franz Liszt. In 1857, Hans von Bülow (Liszt's son-in-law) gave the first public performance on a Bechstein grand piano by performing Liszt's Piano Sonata in B minor in Berlin.

By 1870, with endorsements from Franz Liszt and Hans von Bülow, Bechstein pianos had become a staple in many concert halls and private mansions. By that time three piano makers, all of which were founded in 1853, became established as the industry leaders across the world: Bechstein, Blüthner and Steinway & Sons.

In 1881, Bechstein began supplying pianos to Queen Victoria. A gilded art-case piano was delivered to Buckingham Palace, followed by several more Bechstein pianos to Windsor Castle and other royal residences. By January 1886 they were among the piano manufacturers holding a royal warrant as a supplier to the Queen. Several British embassies across the world acquired Bechstein pianos.

In 1885, Bechstein opened a branch in London, that eventually grew to become the largest showroom and dealership in Europe. In 1889 he moved to 40 Wigmore Street, taking over the property of H. J. Cave & Sons. By 1890, showrooms opened in Paris, Vienna, and Saint Petersburg. On 31 May 1901, Bechstein Hall, built at a cost of £100,000, opened next to the company's London showroom at 36–40 Wigmore Street. Between 1901 and 1914, C. Bechstein was the largest piano dealership in London. At that time, Bechstein was patronized by the tsars of Russia, the royal families of Spain, Belgium, the Netherlands, Italy, Sweden, Norway, Austria and Denmark, and other royalty and aristocracy. The list of royal clients of Bechstein may be found on the soundboard of vintage Bechstein pianos made before the Second World War. The list is part of the original Bechstein trademark logo; it can be seen under the strings in the centre of a piano's soundboard.

The years from the 1870s through 1914 brought Bechstein their most dramatic increase in sales. In 1880 a second Bechstein factory was opened in Berlin, and the third factory opened in 1897 in Berlin-Kreuzberg. Production reached 3,700 pianos annually in 1900, and 4,600 in 1910, making Bechstein the largest German manufacturer of high-end pianos. At that time, about three quarters of production went to international markets, especially Britain and the Commonwealth, and Russia.
