Kenneth Douglas Caillat is an American record producer. He is best known for engineering the Fleetwood Mac albums Rumours, Tusk, Mirage, Live, and The Chain Box Set. He is the father of singer Colbie Caillat.

Rumours is the eleventh studio album by the British-American rock band Fleetwood Mac, released on 4 February 1977 in the United States and on 11 February 1977 in the United Kingdom by Warner Bros. Records. Largely recorded in California in 1976, it was produced by the band with Ken Caillat and Richard Dashut. The recording sessions took place as the band members dealt with breakups and struggled with heavy drug usage, both of which shaped the album's direction and lyrics.
