Ricardo López (January 14, 1975 – September 12, 1996), also known as the "Björk stalker", was a Uruguayan-American pest control worker who attempted to kill Icelandic musician Björk in September 1996.

López developed an obsession with Björk in 1993, and became angry over her relationship with musician Goldie. Over the course of nearly nine months, López made a video diary musing about Björk and other topics at his apartment in Hollywood, Florida. On September 12, 1996, he mailed a letter bomb rigged with sulfuric acid to her residence in London, then returned home and filmed his suicide. Police found López's body and diaries four days later; they contacted the British police, who intercepted the package. Björk was unharmed.
