Locust Abortion Technician is the third full-length studio album by American rock band Butthole Surfers, released in March 1987. All songs were written and produced by Butthole Surfers, except for "Kuntz", which was by Thai artists Phloen Phromdaen and Kong Katkamngae, who were originally uncredited for their work. The album was originally released as vinyl on Touch and Go, and was remastered to CD on Latino Buggerveil in 1999.

Locust Abortion Technician's front cover illustration of two clowns playing with a dog was painted by Arthur Sarnoff, entitled "Fido and the Clowns".

Kurt Cobain listed it in his top 50 albums of all time. It is also featured in Robert Dimery's 1001 Albums You Must Hear Before You Die. In 2018, Pitchfork included the album on their list of "The 200 Best Albums of the 1980s".
