A Knight banneret is a higher rank of knight than a knight bachelor, but a lower rank than a baron or baronet. In English custom the rank of knight banneret can only be conferred by the soverign on the field of battle, though there may be some technical exceptions to this, such as when his standard is on the field of battle he may be regarded as being present though he is not, and his proxy may be regarded as a sufficient substitution for his presence.

Knights banneret are one of the groups eligible to bear supporters in English heraldry .
