thumb|Beaulah Bar in [[De Waterkant, Cape Town, takes its name from the Gayle word for "beautiful".]]

Gayle, or Gail, is an English- and Afrikaans-based gay argot or slang used primarily by English and Afrikaans-speaking homosexual men in urban communities of South Africa, and is similar in some respects to Polari in the United Kingdom, from which some lexical items have been borrowed. The equivalent language used by gay South African men who speak Bantu languages is called IsiNgqumo, and is based on a Nguni lexicon.

Gayle originally manifested as moffietaal (Afrikaans: literally, "homosexual language") in the drag culture of the Cape Coloured community in the 1950s. It permeated into white homosexual circles in the 1960s and became part of mainstream white gay culture.
