"Time Has Come Today" is a hit single by the American soul group the Chambers Brothers, written by Willie & Joe Chambers. The song was recorded in 1966, released on the album The Time Has Come in November 1967, and as a single in December 1967. Although the single never quite reached the top ten in America, spending five weeks at No. 11 on the Billboard Hot 100 in the fall of 1968, it is now considered one of the landmark rock songs of the psychedelic era.

The song has been described as psychedelic rock,psychedelic soul and acid rock, and features a fuzz guitar twinned with a clean one. Various other effects were employed in its recording and production, including the alternate striking of two cow bells producing a "tick-tock" sound, warped throughout most of the song by reverb, echo and changes in tempo. It quotes several bars from “The Little Drummer Boy” at 5:40 in the long version.

The song has appeared in many films. Director Hal Ashby used all 11:06 as the backdrop to the climactic scene when Captain Robert Hyde (Bruce Dern) "comes home" to an unfaithful wife (Jane Fonda) in the 1978 Academy Award winning film Coming Home.

Other films it has also been used in include:
