"I Don't Want to Know" is a song written by Stevie Nicks which was first released by the British-American rock band Fleetwood Mac on their 1977 album Rumours.

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.
