Rengay is a form of linked verse derived from the Japanese renga or renku. The form was devised by Garry Gay in California in 1992. A rengay consists of six thematic haiku-like verses and is normally composed by two or three poets, although solo and six-person rengay are not uncommon. In the 30 years since its invention several hundred rengay have been published, primarily in English, and two competitions for rengay have been established in the United States.
