Twelve Dreams of Dr. Sardonicus is the fourth album by the American psychedelic rock group Spirit. It was produced by David Briggs, who is best known for his work with Neil Young. The original LP was released in 1970 by Epic. It peaked at #63 on the Billboard 200 in February 1971—the band's lowest charting album to that point—and spent 14 weeks on the chart. However, with strong catalog sales it also became the band's only album to be certified Gold in the U.S., achieving that status in 1976. The album was re-issued on CD in 1996 by Sony in remastered form, with bonus tracks.
