The quatrefoil is a four-lobed floral or leaf-like charge in heraldry, traditionally associated with harmony, good fortune, faith, and natural beauty. Its name means “four leaves,” and its balanced form gives it a strong sense of order and completeness. In coats of arms, it may suggest growth, renewal, prosperity, and a well-rooted family line. Because it resembles a stylized flower, clover, or architectural ornament, it can also carry associations with fertility, grace, and the cultivated beauty of medieval design. Its symmetry makes it especially effective as a small repeated charge, a badge, or a decorative element on borders, ordinaries, and crests.

The quatrefoil also has important religious and architectural associations. In Christian art and Gothic architecture, quatrefoil forms appear in tracery, windows, tiles, and manuscript decoration, often suggesting divine order, the four Evangelists, the four corners of the earth, or the harmony of creation. Heraldically, the charge is related to the trefoil, cinquefoil, and huitfoil, each distinguished by the number of lobes or leaves. Its meaning may vary depending on tincture and context. A green quatrefoil may emphasize nature and flourishing life, while a gold one may suggest honor, generosity, or noble promise.

Reliable examples are found in medieval and modern armory where quatrefoils appear as simple floral charges, decorative badges, or repeated devices. Variants such as the cinquefoil are more common, but the quatrefoil is well recognized in heraldic terminology and visual design. Its close connection with Gothic ornament makes it particularly suitable for ecclesiastical, academic, and architectural arms.
