Gillette is a brand of men's and women's safety razors and other personal care products including shaving supplies, owned by the multi-national corporation Procter & Gamble (P&G).

​

Based in Boston, Massachusetts, United States, it was owned by The Gillette Company, a supplier of products under various brands until that company merged into P&G in 2005. The Gillette Company was founded by King C. Gillette in 1901 as a safety razor manufacturer.

​

Under the leadership of Colman M. Mockler Jr. as CEO from 1975–91, the company was the target of three takeover attempts, from Ronald Perelman and Coniston Partners. On October 1, 2005, Procter & Gamble finalized its merger with the Gillette Company.
