NOHAB (Nydqvist & Holm AB) was a manufacturing company based in Trollhättan, Sweden.

The company was founded by Antenor Nydqvist, Johan Magnus Lidström and Carl Olof Holm in 1847 as Trollhättans Mekaniska Verkstad, making hydro turbines. In 1865, the company made its first steam locomotive and in 1912 the 1,000th locomotive left the factory.

In 1916 the company was reconstituted as a limited company and became NOHAB.

In 1930, NOHAB started manufacturing the Bristol Jupiter aircraft engine, under licence from the Bristol Aeroplane Co. A couple of years later the aircraft engine division of NOHAB and AB Svenska järnvägsverkstäderna (Swedish Railway Workshop Limited), in Linköping, formed the aircraft manufacturer SAAB.

1930-1936 they built Ljungström steam turbine locomotives.

1948 Nydqvist and Holm acquired the diesel engine production of Atlas Diesel Co.

In the 1950s, NOHAB started manufacturing diesel locomotives under licence from Electro-Motive Division of General Motors.

In addition to locomotives and aircraft NOHAB was a major manufacturer of turbines for power plants and well known for medium size marine diesel engines. NOHAB also manufactured the hulls for the S-tank.

1978 Bofors sold 51 percent of the NOHAB diesel business to Wärtsilä. The remaining shares were acquired in 1984. It became known as Wärtsilä Nohab.

The company went bankrupt in 1979.
