Rock Love: Rock Love is the sixth album by American rock band The Steve Miller Band, released in 1971.

Bobby Winkelman was in the band (having moved back to rhythm guitar) during the live recordings on the album's first side, but is not credited on the album cover.

Subsequent touring and critical praise earned the band a deal with Lookout, culminating in the release of an EP, album, and several videos, leading up to, according to many critics, their strongest album to that point, "The World & Everything in It".  In 2004, Morphius released a retrospective compiling the band's earlier work including "The Five Dollars EP", the now out-of-print "900 Miles of Fucking Hell" EP, as well as various unreleased tracks entitled Two Thousands.  In 2008, with a new lineup that included Pat Martin on bass and guest guitarist Doug Gillard, the band released their third full length The Oranges Band are Invisible.
