Boosey & Hawkes is a British music publisher, purported to be the largest specialist classical music publisher in the world. Until 2003, it was also a major manufacturer of brass, string and woodwind musical instruments.

Formed in 1930 through the merger of two well-established British music businesses, Boosey & Hawkes controls the copyright to much major 20th-century music, including works by Leonard Bernstein, Benjamin Britten, Aaron Copland, Sergei Prokofiev, and Igor Stravinsky. It also publishes many prominent contemporary composers, including John Adams, Karl Jenkins, James MacMillan, Mark-Anthony Turnage, and Steve Reich.

With subsidiaries in Berlin and New York, the company also sells sheet music via its online shop.
