Ricoh Company, Ltd.（株式会社リコー， Kabushiki-gaisha Rikō） (TYO: 7752) or Ricoh, is a Japanese company that was established on 6 February 1936 as Riken Kankoshi Co., Ltd.

Ricoh produces electronic products, primarily cameras and office equipment such as printers, photocopiers and fax machines. In the late 1990s through early 2000s, the company grew to become the largest copier manufacturer in the world. During this time, Ricoh acquired Savin, Gestetner, Lanier, Rex-Rotary, Monroe, and Nashuatec. Although the Monroe brand was discontinued, products continue to be marketed worldwide under the rest of these brand names. In 2006, Ricoh acquired the European operations of Danka.

Throughout the late 1980s and early 1990s, Ricoh was the primary manufacturer of Pitney-Bowes copiers. They have also manufactured copiers for Toshiba, fax machines for AT&T and Omnifax, as well as a wide variety of equipment for numerous other companies including duplicators for AB Dick.

In 2003 Ricoh purchased naming rights to the CNE Coliseum (now know as Ricoh Coliseum) in Toronto, Canada.

In 2005 Ricoh gave over £10 million to Coventry City Football Club to help complete the club's stadium. Accordingly now titled the Ricoh Arena, the stadium bears various reminders of the company's generosity, ranging from 100 ft signs on the roof to centimetre-long logos on match day programmes.

On January 25, 2007, Ricoh announced purchase of IBM Printing Systems Division for $725 million and investment in 3-year joint venture to form new Ricoh subsidiary, InfoPrint Solutions Company, with 51% share.
