Robert Bosch GmbH or Bosch, is a German multinational engineering and electronics company headquartered in Gerlingen, near Stuttgart, Germany. It is the world's largest supplier of automotive components measured by 2011 revenues. The company was founded by Robert Bosch in Stuttgart in 1886.

Bosch comprises more than 350 subsidiary companies. In addition to automotive components, which generate around 60% of its revenues, Bosch produces industrial machinery and hand tools.

Although most of the company's plants and employees are located in Germany (112,300 employees), Bosch is a worldwide company.

Bosch also has an R&D facility in Bangalore, India. This is Bosch's largest R&D facility outside its home market of Germany. In September 2014, Bosch announced the launch of a locally-developed eye-care solution in India. The company’s new eye screening and detection system offers a combination of hardware and software and provides affordable eye care.
