The pike in heraldry can refer either to the long thrusting weapon used by infantry or to the freshwater fish, and its meaning depends entirely on how it is drawn and blazoned. As a weapon, the pike represents military readiness, discipline, defense, and service in organized warfare. It was especially associated with foot soldiers, civic militias, guards, and disciplined ranks of infantry who relied on unity and steadiness rather than individual display. In a coat of arms, a pike may therefore suggest courage, vigilance, martial duty, or a family connection with soldiering, town defense, or the keeping of order.

When the pike is a fish, its symbolism belongs to water, rivers, lakes, fishing, and local geography. The fish is known as a powerful predator, so it can suggest alertness, strength, resourcefulness, and mastery of a watery environment. Fish charges in heraldry often point to coastal or river communities, fisheries, trade, Christian symbolism, or abundance. A pike fish may be especially appropriate for armigers or towns connected with inland waterways, freshwater fishing, or names that lend themselves to visual wordplay. Its meaning may be strengthened when shown with waves, boats, nets, hooks, or other aquatic charges.

Both forms of the pike appear within broader heraldic traditions. Weapon pikes belong to the same family as spears, lances, halberds, and polearms, while pike fish belong with salmon, trout, dolphins, and other aquatic creatures used in civic and family arms. Because the word has two distinct heraldic possibilities, accuracy in artwork and blazon is important.
