Logitech International S.A. (/ˈlɒɪtɛk/ LOJ-ih-tek; commonly referred to as Logitech or Logi; stylized as logitech, previously LOGITECH) is a Swiss provider of personal computer and mobile peripherals, with its headquarters in Lausanne, Switzerland and administrative headquarters in Newark, California. In addition to its Swiss and American facilities, the company has offices throughout Europe, Asia and the rest of the Americas. Logitech’s sales and marketing activities are organized into three geographic regions: Americas, Europe, Middle East and Africa, and Asia Pacific.

The company develops and markets personal peripherals for PC navigation, video communication and collaboration, music and smart homes. This includes products like keyboards, mice, tablet accessories, webcams, Bluetooth speakers, universal remotes and more.

The name Logitech is derived from the French word for software, “logiciel”. In Japan, it was established as Logicool to avoid conflict with the Logitec brand.

Logitech was co-founded in Apples, Vaud, Switzerland, in 1981 by two Stanford alumni, Daniel Borel and Pierluigi Zappacosta, and a former Olivetti engineer, Giacomo Marini.
