Stoned Soul Picnic is the third album by the American pop group the 5th Dimension, released in 1968. Early versions of the album had a lyric sheet inserted in the sleeve. Stoned Soul Picnic was the third and final album by the group to be issued in both mono (SCM 91002) and stereo (SCS 92002) as monaural albums were being phased out during its release in 1968. As a result, mono copies were pressed in a limited quantity and are considered rare in the collectors market.
