The pike as a weapon is a strong martial symbol in heraldry, associated with military discipline, defense, vigilance, and the courage of the common soldier. A pike was a long thrusting polearm used by infantry, especially from the late medieval period through the early modern era, when tightly ordered ranks of pikemen could stop cavalry and hold ground with remarkable effectiveness. In coats of arms, the pike may therefore represent readiness for battle, steadfast service, obedience to command, and the power of organized defense. Unlike a sword, which often suggests personal honor or knightly status, the pike points more directly to collective strength and disciplined protection.

Heraldically, a pike may appear upright, crossed in saltire, held by an arm, combined with banners or drums, or placed with other weapons such as halberds, spears, muskets, or swords. Its meaning often depends on the setting. Crossed pikes can suggest military preparedness, civic guard service, or a fortified town defended by militia. A pike with a banner may indicate command, regiment, or loyalty to a cause. In civic heraldry, polearms frequently recall town watches, guilds, arsenals, historic battles, or the duty of citizens to defend walls, gates, and liberties.

Reliable examples are found within the broader heraldic use of spears, lances, halberds, and other polearms, especially in European civic and military arms. Pikes are also common in regimental badges, militia emblems, and early modern military symbolism because they were central to infantry warfare. The term must be distinguished from the pike fish, since the two have entirely different meanings in blazon and artwork.
