Semper Fidelis

Semper Fidelis. This Latin phrase, translating to "Always Faithful," is a widely recognized motto signifying unwavering loyalty and fidelity. Its most famous association is with the United States Marine Corps, where it serves as an official creed deeply embedded in the institution's identity. The motto also appears in various other military, civic, and cultural contexts across the Western world, from European regiments to municipal coats of arms.

Etymology and meaning

The phrase originates from the classical Latin language, combining the adverb semper ("always") with the adjective fidelis ("faithful" or "loyal"). It belongs to a tradition of concise Latin mottos adopted by military units, educational institutions, and noble families to express core virtues. The concept of fidelity it conveys is multifaceted, encompassing loyalty to one's country, comrades, duty, and honor. Similar classical mottos include Semper Paratus used by the United States Coast Guard and Semper Supra adopted by the United States Space Force.
