Thigmotactic is a 2008 album by sound collage group Negativland. Unlike previous efforts by the band, it is primarily the expression of one member, Mark Hosler, though other members contributed, as did Thomas Dimuzio. Hosler created the bulk of its audio content as well as the visual collages and assemblages of found objects that are pictured in the liner notes. It is also notable as the band's "first entirely song-based project" and features fifteen songs and two instrumental pieces.
The title Thigmotactic refers to thigmotaxis, an instinctive reflex in response to physical touch, as mentioned in a passage from Ann Zwinger's The Mysterious Lands about a desert lizard with this property. These sentences are excerpted on the inside of the CD cover.
