The middle coat of arms of the Grand Duchy of Luxembourg prior to 2000 is a heraldic symbol representing the ruling monarchy. This particular version, used before the year 2000, features a blue shield bearing three gold lions passant guardant (walking and facing the dexter) on a field. The shield is surmounted by a ducal coronet of five fleurs-de-lis, indicating a grand duke's status. This version of the coat of arms reflects the historical heraldry of the House of Nassau, the reigning dynasty of Luxembourg since 1890. The design has since been modified in 2000, but this earlier version remains significant in the Grand Duchy's heraldic tradition.
