A gyron is a triangular heraldic ordinary having an angle at the fess point and the opposite side at the edge of the escutcheon. A shield divided into gyrons is called gyronny, the default is typically of eight if no number of gyrons is specified. The word gyron is derived from Old French {{Lang|fro|giron}}, meaning 'gusset'.{{cite encyclopedia |title=Gyron |encyclopedia=Concise Oxford English Dictionary |edition=11th |year=2008 |location=Oxford |publisher=University Press |ISBN=9780199548415}} When a single gyron extends across so the tip touches the edge of the coat of arms, forming a square, it is called an esquire.{{cite book |first=Thomas |last=Robson |title=The British herald, or Cabinet of armorial bearings of the nobility & gentry of Great Britain & Ireland|year=1830 |quote=Esquire, equire, or squire, by Edmondson considered the same as the gyron, which must be wrong, because the gyron only extends to the centre fesse point; whereas the esquire, though of the same shape, runs across the whole field.}}{{cite book|editor-first=Stephen|editor-last=Friar|title=A New Dictionary of Heraldry|location=London|year=1987|publisher=Alphabooks/A&C Black|isbn=0 906670 44 6|page=139}}

The gyron rarely appears singly, but as a variation of the field, gyronny coats appear frequently. These most often appear as eight roughly equal parts, but occasionally a coat gyronny of six, ten, twelve or more parts may be specified.{{cite book |last=Fox-Davies |first=Arthur Charles |year=1909 |title=A Complete Guide to Heraldry |url=https://archive.org/details/cu31924029796608 |location=New York |publisher=Dodge Publishing Co |page=[https://archive.org/details/cu31924029796608/page/n164 137]}}
