Vanishing Lessons is the fourth studio album by the American Christian metal band Tourniquet.

It was the first Tourniquet album to feature then-lead vocalist Luke Easter, who joined the band in 1993.

The songs "Bearing Gruesome Cargo," "Acid Head" and "K517" were included on the Tourniquet/Mortification Collector's Edition CD Single in 1994; the disc also featured tracks with Ted Kirkpatrick talking about Tourniquet and included material from the Australian Christian metal band Mortification's Live Planetarium and Blood World releases.

This album was later bundled with 1992's Pathogenic Ocular Dissonance and released on KMG Records in 2000.

Vanishing Lessons was independently re-released on Pathogenic Records with digital remastering, bonus tracks, and new artwork in 2004.
