In heraldry, the term attitude describes the position in which a figure (animal or human) is emblazoned as a charge, a supporter, or as a crest. The attitude of a heraldic figure always precedes any reference to the tincture of the figure and its parts. Some attitudes apply only to predatory beasts, exemplified by the beast most usual to heraldry – the heraldic lion; other terms apply to docile animals, such as the doe, usually emblazoned as a "hind".

Other heraldic attitudes, such as volant (flying), describe the positions of birds, exemplified by the bird most usual to heraldry – the heraldic eagle; moreover, birds also are described by the positions of their wings. The term naiant (swimming) applies to fish, swans, ducks, and geese. The term segreant is applied to the griffin, as an approximation of rampant, and is applied to the dragon. Animal figures are positioned in profile, facing dexter (the viewer's left), and persons are shown affronté (facing the viewer), but the blazon might specify other attitudes.

Animals and animal-like creatures are presumed to be shown in profile facing dexter. This attitude is standard unless otherwise stated in the blazon. As a warrior will usually carry a shield in the left hand, the animal shown on the shield will then face toward the knight's body. Humans and human-like beings are presumed to be shown affronté. The heraldic terms dexter ('right') and sinister ('left') represent the shield bearer's perspective, not the viewer's.

Many attitudes commonly met with in heraldic rolls apply specifically to predatory beasts, while others may be better suited to the docile animals. These will each be discussed in detail below.

A blazon may also specify the position of a beast's head, differently coloured parts (such as teeth, claws, tongue, etc.), or the shape or position of its tail. A beast may be "armed" (horns, teeth and claws) or "langued" (tongue) of a tincture, while a stag may be "attired" (antlers) or "unguled" (hooves) of a tincture. The tail may be forked (queue fourchée) or doubled (double-queued). In addition to the below, there may be rare or, arguably, not entirely standard attitudes, such as a snorting bison.

A beast rampant (Old French: "rearing up") is depicted in profile standing erect with forepaws raised. The position of the hind legs varies according to local custom: the lion may stand on both hind legs, braced wide apart, or on only one, with the other also raised to strike; the word rampant is sometimes omitted, especially in early blazon, as this is the most usual position of a carnivorous quadruped. Note: the term segreant denotes the same position, but implies a particular wing position and is only used in reference to winged quadrupeds such as griffins and dragons. Rampant is the most frequent attitude of quadrupeds, and as supporters they are rarely seen in any other attitude. Forcené is the term for this position when applied to horses or unicorns.

A beast passant (Old French: "striding") walks toward dexter (the viewer's left) with the right forepaw raised and all others on the ground. Early heralds held that any lion in a walking position must necessarily be a "leopard", and this distinction persists in French heraldry; however, this use of the term leopard has long since been abandoned by English heralds. A "Lion of England" denotes a lion passant guardant Or, used as an augmentation. The Welsh flag features a dragon passant. For stags and other deer-like beasts of chase, the term trippant is used instead of passant.

A beast sejant or sejeant (Middle French: seant, siégeant, "sitting") sits on its haunches, with both forepaws on the ground.
