Spandex, Lycra or elastane is a synthetic fiber known for its exceptional elasticity. It is stronger and more durable than natural rubber. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia. When introduced in 1962, it revolutionized many areas of the clothing industry.

It is the preferred name in North America ; in continental Europe it is referred to by variants of "elastane", i.e. élasthanne ( France ), Elastan ( Germany ), elastano ( Spain ), elastam ( Italy ) and elastaan ( Netherlands ), and is known in the UK, Ireland, Portugal, Spain, Brazil, Argentina, Australia, New Zealand and Israel primarily as Lycra.
