C.F. Martin & Company (Martin) is a US guitar manufacturer that was established in 1833 by Christian Frederick Martin. Martin is renowned for its high quality acoustic guitars, and is arguably the world's pre-eminent mass manufacturer of flattop acoustics with models that retail for thousands of dollars and vintage instruments that often fetch six figures at resale. The company also made several models of electric guitars and electric basses.
The company has been run by the Martin family for all of its history; its current chairman and CEO, C.F. 'Chris' Martin IV, is the great-great-great-grandson of the founder. Many characteristic features of the modern flatop steel strung acoustic guitar were first introduced by the firm. Some influential creations of the company include the Dreadnought body style and scalloped X bracing.
The company's headquarters and primary factory are in Nazareth, Pennsylvania, located in the Lehigh Valley region of the state.
