Garry Gay (born Garry Gene Gay, March 28, 1951, Glendale, California, U.S.A.) professional photographer and haiku poet and organizer. He was a leading member of the Leanfrog haiku group in Oakland, Calif., in the late 1970s and early 80s and was a cofounder and first president of the Haiku Poets of Northern California, 1989–90 (and president again in 2001–2011, and current president). In 1991 he was elected president of the Haiku Society of America, the first not to hail from the East Coast. He was also a cofounder of the Haiku North America series of haiku conferences and chairs the advisory board for the American Haiku Archives in Sacramento, Calif. Gay has published several chapbooks and edited a number of haiku anthologies. He is credited with the invention of rengay, a popular linked-verse form. He lives in Santa Rosa, California.

The Garry Gay Rengay Award was added to the list of annual contests sponsored by the Haiku Society of America in 2020. Named after the inventor of the form, the HSA contest is only the second international-level competition for rengay.

Rengay is a form of linked verse created as an alternative to Japanese renga or renku. The form was devised by Garry Gay in California in 1992. A rengay consists of six thematic haiku verses and is normally composed by two or three poets, although solo and six-person rengay are not uncommon. Since its invention many hundreds of rengay have been published, primarily in English, and two competitions and two journals for rengay have been established in the United States.
