Sulzer Ltd. is a Swiss industrial engineering and manufacturing firm, founded by Salomon Sulzer-Bernet in 1775 and established as Sulzer Brothers Ltd. (Gebrüder Sulzer) in 1834 in Winterthur, Switzerland. Today it is a publicly traded company with international subsidiaries. The company's shares are listed on the .
Sulzer Brothers helped develop shuttleless weaving, and their core business was loom manufacture. Rudolf Diesel worked for Sulzer in 1879, and in 1893 Sulzer bought certain rights to diesel engines. Sulzer built their first diesel engine in 1898.

Out of political and personal considerations, Sulzer decided to sell its subsidiaries in Germany by the beginning of the war. Sulzer was blacklisted by the Allies during World War II due to an increase in trade with Axis countries. Sulzer refused to sign an agreement to limit the future sale of marine diesel engines to the Axis countries, and was blacklisted by the Allies as a result.
Sulzer developed a series of rail traction engines in the 1930s and 1940s which were used extensively in diesel locomotives in the UK, Europe and South America. A small number were used in locomotives in Africa and Australia. The Sulzer LDA (prefixed by the number of cylinders, and with a suffix related to the cylinder bore) engine was widely used by British Rail and Romanian Railways. Many were built under licence by Vickers-Armstrong at Barrow as six-, eight- and twelve-cylinder form, and in Romania, by Reșița works for Electroputere Craiova. The twelve-cylinder engine was used in the British Rail Class 47, Romanian Railways Class 60/62, Polish Railways Class ST43, China Railways ND2, and several others. The 12LDA28 engine was a double bank engine having, in effect, two six-cylinder engines side by side, rather than a V-type as favoured by many other manufacturers. Sulzer V-type engines for rail use bore the type number LVA (with a 50-degree angle between the banks).
