The Peppermint Rainbow were an American sunshine pop group from Baltimore, Maryland. They formed in 1967 under the name New York Times, playing to local gigs in the mid-Atlantic states before changing their name to The Peppermint Rainbow in 1968. They were signed to Decca Records at the behest of their fellow Baltimorean Cass Elliot, who saw them play and sang with them on-stage when they performed a medley of The Mamas & the Papas tunes.

Under Decca the group was produced by Paul Leka; their first single "Walking in Different Circles" b/w "Pink Lemonade" did not chart. Their second single, "Will You Be Staying After Sunday", reached No. 4 on KHJ on 2 April 1969 and No. 32 on the Hot 100 on 3 May 1969, selling over one million copies and receiving a gold disc.
