Our Little Secret is the third studio album from Belgian electronic band Lords of Acid. It was released in 1997 on Antler-Subway Records. Both musically and lyrically, Lords of Acid maintain the industrial music and sexually charged songs found on their previous album Voodoo-U. Lead vocal duties on Our Little Secret were performed by Jade 4 U. The front CD cover is a photo of a woman from the waist up, while the unfolded CD cover booklet is the completed full-body photograph which reveals an outline of a penis in her blue jeans.

Displaying the band's trademark tongue-in-cheek humor, the back cover of the album presented Our Little Secret as a live recording of a classical music concert, as presented by "The Lords of Acid Orchestra". The song titles are presented with faux, intentionally pretentious parentheticals pertaining to classical pieces.

Our Little Secret was the first Lords of Acid album to hit the U.S. Billboard 200, peaking at number 100. As was the case with their Lust and Voodoo-U albums, Our Little Secret was re-issued in 2001 as a "Stript" version, which removed all vocals. The album features one of their most recognizable hits, "Pussy".
