There are three bands with this name.

1) Suicide is an American duo that was one component of the late 1970's punk scene on the Lower East Side of New York City, USA. The band consists of Alan Vega and Martin Rev, who used farfisa organs, synthesizers, and drum machines to create their trademark sound. While widely unconsidered and largely disliked during their beginnings, their 1977 self-titled album is considered to be one of the most influential albums of the punk movement and has influenced countless others, including The Jesus and Mary Chain, She Wants Revenge and R.E.M. The grander influence of Suicide's electronic primitivism can be heard in the later music movements of synthpop, techno, and industrial music.

2) Suicide is a band from Ankara, Turkey, considered to be the pioneer of the death metal in Turkey. Suicide was founded by guitar player Erkan Tatoglu and his friends in 1989. In 1991, the first concert was given in Ankara, Talip cinema where the band played to an audience of approximately 1300 people. After so many changes in the line up, Erkan moved to vocals and Hakan Kuscu joined the band as the lead guitarist in 1994. Esad Erbil joined in 1995 as the bass guitar player. The band's recent line up has formed after Caglar Yurut joined them in 2003. In Turkey, the band took stage in more than 50 concerts mostly in Ankara, Eskisehir, Istanbul, Bursa, Izmir, Kayseri and Mersin. The band, also known as the "Death Metal Titans" in Turkey has an EP called "Spiritual Mess" (2000), a split CD including this EP and an album "One of Your Neighbours" (2004).
