Bochum Welt is the stage name of the Italian electronic musician Gianluigi Di Costanzo. The name Bochum Welt is a combination of the German word for "world" (welt) and the name of a high-powered astral telescope.

Di Constanzo has released numerous records on established record labels. His first single for Aphex Twin's Rephlex label, "Scharlach Eingang" (1994), published by Warner/Chappell Music, was sufficiently accomplished that the British music magazine NME ran an article claiming that Bochum Welt was another of Aphex Twin's myriad alter egos.
