Family coat of arms of Jane Austen, the author, taken from the heraldic bookplate of John Austen Esq. of Broadford, Kent, England — who was either Jane Austen's patrilineal cousin once removed (lived 1716-1807), or her patrilineal second cousin (lived 1777-1851), depending on which one of a father and son is meant.

The blazon is: Or, a chevron gules between three lions' gambs erect erased sable armed of the second. Crest: On a mural crown or, a stag sejant argent, attired or. (A mural crown, unlike many other types of crowns or coronets, is not any sign of aristocracy or nobility; however, the right to bear arms does suggest some degree of family social prominence. According to the 1909 edition of Fox-Davies' "Complete Guide to Heraldry", after the early 19th-century, the English College of Arms granted new mural-crown crests only to high-ranking officers in the British army.)

Note that the ornamental winged child's head at the bottom of the heraldic shield is not actually part of the coat of arms. A heraldic display for Jane Austen individually would probably have been shown on the "lozenge" (or diamond shape) considered appropriate for a woman, rather than on a shield, and without the crest above.

The Latin motto, "QUI INVIDIT MINOR EST", can be translated as "Who(ever) envies (me) is lesser/smaller (than I am)".
