Head Hunters is the twelfth studio album by American pianist, keyboardist and composer Herbie Hancock, released October 26, 1973, on Columbia Records. Recording sessions for the album took place in the evening at Wally Heider Studios and Different Fur Trading Co. in San Francisco, California. Hancock is featured with woodwind player Bennie Maupin from his previous "Mwandishi" sextet and three new collaborators – bassist Paul Jackson, percussionist Bill Summers, and drummer Harvey Mason. The latter group of collaborators, which would go on to be known as the Headhunters, also played on Hancock's subsequent studio album Thrust (1974). All of the musicians (with the exception of Mason) play multiple instruments on the album.

The album was a commercial and artistic breakthrough for Hancock, crossing over to funk and rock audiences and bringing jazz-funk and jazz fusion to mainstream attention, peaking at number 13 on the Billboard 200. Today the album is regarded as a landmark of fusion and has influenced artists in numerous other genres. In 2008, the Library of Congress inducted it into the National Recording Registry for being "culturally, historically or aesthetically important".

Head Hunters followed three experimental albums by Hancock's "Mwandishi" sextet: Mwandishi, Crossings, and Sextant, released between 1971 and 1973. He later reflected on moving away from this style:

I began to feel that I had been spending so much time exploring the upper atmosphere of music and the more ethereal kind of far-out spacey stuff. Now there was this need to take some more of the earth and to feel a little more tethered; a connection to the earth. ... I was beginning to feel that we (the sextet) were playing this heavy kind of music, and I was tired of everything being heavy. I wanted to play something lighter.

For the new album, Hancock assembled a new band, the Headhunters, of whom only woodwind player Bennie Maupin had been a member of the "Mwandishi" sextet. Hancock handled all synthesizer parts himself, having shared these duties with Patrick Gleeson on Crossings and Sextant, and decided against the use of guitar altogether in favor of the Hohner Clavinet, one of the defining sounds on the album. The new band featured a tight rhythm section composed of Paul Jackson (bass guitar) and Harvey Mason (drums), creating a relaxed funk sensibility that gave it an appeal to a wider audience.

Of the four tracks on the album, "Watermelon Man" was the only one not written for the album. A hit from Hancock's hard bop days, originally appearing on his debut Takin' Off (1962) and later covered by Mongo Santamaría, it was reworked by Hancock and Mason for this album, featuring Bill Summers blowing into a beer bottle in imitation of the hindewho flute used by the Mbuti Pygmies of Zaire. The track features heavy use of African percussion. "Sly" was dedicated to Sly Stone of Sly and the Family Stone. "Chameleon" features a famous bassline played by Hancock on an ARP Odyssey synthesizer. Closing track "Vein Melter" is a slow-burner, predominantly featuring Hancock on Rhodes piano and Maupin on bass clarinet. Heavily edited versions of "Chameleon" and "Vein Melter" were released as two sides of a 45 RPM single.

The Headhunters band, with Mike Clark replacing Mason, worked with Hancock on a number of other albums, including Thrust (1974), Man-Child (1975), and Flood (1975). The subsequent albums Secrets (1976) and Sunlight (1977), had widely diverging personnel. The Headhunters, with Hancock featured as a guest soloist, produced the albums Survival of the Fittest (1975) and Straight from the Gate (1978), the first of which was produced by Hancock and included the hit "God Make Me Funky".
