"Mecha-Streisand" is the 12th episode of the first season of the animated television series South Park. It originally aired on Comedy Central in the United States on February 18, 1998. In the episode, Barbra Streisand obtains the Diamond of Panthios from the South Park boys and transforms into a giant mechanical dinosaur called Mecha-Streisand. She is ultimately defeated by The Cure frontman Robert Smith, who himself transforms into a giant moth monster.

The episode was written by series co-creators Trey Parker and Matt Stone along with writer Philip Stark, and was directed by Parker. "Mecha-Streisand" was a parody of the Japanese Godzilla monster movie franchise, with Streisand resembling Mechagodzilla and Smith resembling Mothra. Actor Sidney Poitier and film critic Leonard Maltin also appear as giant creatures resembling Gamera and Ultraman, respectively.

According to Nielsen ratings, "Mecha-Streisand" was seen by 5.4 million viewers, a record high viewership for a South Park episode at the time. Barbra Streisand was critical of the series and her role in "Mecha-Streisand", although Leonard Maltin complimented his portrayal.

The Cure are an English alternative rock band formed in Crawley, West Sussex in 1976. The band has experienced several line-up changes, with frontman, vocalist, guitarist and principal songwriter Robert Smith being the only constant member. The Cure first began releasing music in the late 1970s with its debut album Three Imaginary Boys (1979); this, along with several early singles, placed the band as part of the post-punk and New Wave movements that had sprung up in the wake of the punk rock revolution in the United Kingdom. During the early 1980s, the band's increasingly dark and tormented music helped form the gothic rock genre.

After the release of Pornography (1982), the band's future was uncertain and Smith was keen to move past the gloomy reputation his band had acquired. With the 1982 single "Let's Go to Bed" Smith began to place a pop sensibility into the band's music (as well as a unique stage look). The Cure's popularity increased as the decade wore on, especially in the United States where the songs "Just Like Heaven", "Lovesong" and "Friday I'm in Love" entered the Billboard Hot 100 chart. By the start of the 1990s, The Cure were one of the most popular alternative rock bands in the world. The band is estimated to have sold 27 million albums as of 2004. The Cure have released thirteen studio albums, 10 EPs and over thirty singles during the course of their career. Since 2010, they have been working on a fourteenth studio album.
