File:Tudor Rose.svg is a double rose.]]

Double rose is a term used for a rose in heraldry when it has not only five petals, but additionally five petals within the outer petals. It is in essence a combination of two roses, one on top of the other. A standard heraldic rose should not be depicted this way but has only the five outer petals.{{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=286}}

An example of this heraldic charge is the Tudor rose, which is (most usually) a double rose gules and argent, barbed and seeded proper, but as it is so common in English heraldry it is often just blazoned as a "Tudor rose" or a "Tudor rose proper", for instance in the coat of arms of the Royal Borough of Greenwich, London.

In botany, a double rose is a double-flowered variety of the rose, much like the heraldic double rose. These varieties go back to pre-heraldic times.Theophrastus mentioned double roses in his Enquiry into Plants, written before 286 BC.{{cite journal| author=Wang GuoLiang| title=A study on the history of Chinese roses from ancient works and images| journal=Acta Horticulturae | year=2007| volume=751| issue=751| pages=347–356| doi=10.17660/ActaHortic.2007.751.44| url=http://www.actahort.org/books/751/751_44.htm}}
