The "Arms of the Count of Luxembourg" refers to the official heraldic design used by the ruling Count of Luxembourg. This coat of arms is a visual representation of the sovereign's noble status, lineage, and territorial affiliations. Historically, the specific details of the arms can vary based on the reigning Count, but they typically include elements such as a golden lion passant guardant (a rampant lion facing the viewer) on a field of red, representing the Duchy of Luxembourg, and additional symbols representing other territories held by the Count. The coat of arms serves as an important symbol of identity and continuity within the Luxembourgish dynasty.
