The Order of the Holy Spirit (French: Ordre du Saint-Esprit; sometimes translated into English as the Order of the Holy Ghost), is a French order of chivalry founded by Henry III of France in 1578. Today, it is a dynastic order under the House of France.
 It should not be confused with the Congregation of the Holy Ghost or with the religious Order of the Holy Ghost. It was the senior chivalric order of France by precedence, although not by age, since the Order of Saint Michael was established more than a century earlier.
 Although officially abolished by the government authorities in 1830 following the July Revolution, its activities carried on. It is still recognised by the International Commission for Orders of Chivalry.
 Prior to the creation of the Order of the Holy Spirit in 1578 by King Henry III, the senior order of chivalry in France had been the Order of Saint Michael.  The idea flashed to him in Venice, where he had seen the original manuscript of an Order of the Saint Esprit or Droit Desir founded in 1353 by Louis of Anjou, titular king of Jerusalem and Sicily and husband of Joanna, queen of Naples and countess of Provence, and placed under the protection of St. Nicholas of Bari, whose image was reproduced on the pendant of the collar. Henry III realised that the Order of St. Michael had inflated and degraded during the civil wars, and therefore decided to place the new order of the Holy Spirit alongside it and to attribute them together; for this reason who was created knight of the Holy Spirit was called chevalier des ordres du roi. Its membership was initially restricted to a small number of powerful princes and nobles, but this increased dramatically due to the pressures of the Wars of Religion.
 At the beginning of the reign of Henry III, the Order of Saint Michael had several hundred living members, ranging from kings to bourgeois. Recognising that the order had been significantly devalued, Henry III founded the Order of the Holy Spirit on December 31, 1578, thereby creating a two-tier system: the new order would be reserved for princes and powerful nobles, whilst the Order of Saint Michael would be for less eminent servants of the Crown. The new order was dedicated to the Holy Spirit to commemorate the fact that Henry III was elected as King of Poland (1573) and inherited the throne of France (1574) on two Pentecosts.
 
The new order was also identified with the "Order of the Knot" (Ordre du Nœud, also known as Ordre du Saint-Esprit au Droit Désir "Order of the Holy Spirit of the Right Will") which had been founded in 1352/3 by Louis I of Naples. This had been one of the short-lived chivalric orders popular among the high nobility at the time. The statutes of the 14th-century order are preserved as BNF Fr 4274. An elaborate facsimile of this manuscript was produced under Louis XIV.
 During the French Revolution, the Order of the Holy Spirit was officially abolished by the French government, along with all other chivalric orders of the Ancien Régime, although the exiled Louis XVIII continued to acknowledge it. Following the Bourbon Restoration, the order was officially revived, only to be abolished again by the Orleanist Louis-Philippe following the July Revolution in 1830. Despite the abolition of the order, both the Orléanist and Legitimist pretenders to the French throne have continued to nominate members of the order, long after the abolition of the French monarchy itself.
 The King of France was the Sovereign and Grand Master (Souverain Grand Maître), and he made all appointments to the order. Members of the order can be split into three categories:
 Initially, four of the ecclesiastic members had to be cardinals, whilst the other four had to be archbishops or prelates. This was later relaxed so that all eight had to be either cardinals, archbishops or prelates.
 Members of the order had to be Roman Catholic and had to be able to demonstrate three degrees of nobility. The minimum age for members was 35, although there were some exceptions:
 All knights of the order were also members of the Order of Saint Michael. As such, they were generally known by the term Chevalier des Ordres du Roi (i.e. "Knight of the Royal Orders"), instead of the more lengthy Chevalier de Saint-Michel et Chevalier du Saint-Esprit (i.e. "Knight of Saint Michael and Knight of the Holy Spirit").
 The order had its own officers. They were responsible for the ceremonies and the administration of the order.
 Officers of the order were as follows:
 The symbol of the order is known as the Cross of the Holy Spirit (this is a Maltese Cross). At the periphery, the eight points of the cross are rounded, and between each pair of arms there is a fleur-de-lis. Imposed on the centre of the cross is a dove. The eight rounded corners represent the Beatitudes, the four fleur-de-lis represent the Gospels, the twelve petals represent the Apostles, and the dove signifies the Holy Spirit. The Cross of the Holy Spirit was worn hung from a blue riband ("Le cordon bleu").
 Due to the blue riband from which the Cross of the Holy Spirit was hung, the knights became known as Les Cordons Bleus. Allegedly, the banquets after ceremonial occasions were so famous that the expression cordon bleu became synonymous with high quality haute cuisine and, over time, extended to refer to other distinctions of the highest class. The culinary magazine La Cuisinière Cordon Bleu refers to the ribbon, as well as the eponymous network of hospitality and culinary schools. In modern English usage, cordon bleu (/ˌkɔː.dɒ̃ˈblɜː/, also US: /ˌkɔːr.dɒ̃ˈbluː/) is used as an adjective for chefs who are able to cook food to the highest standard as well as the food itself.
Blue Riband sporting events are also sometimes associated with the cordon bleu.[citation needed]
 The badge of the Order is a gold Maltese cross with white borders, each of the eight points ending in a gold ball (points boutonnées) and with a gold fleur-de-lys between each adjacent pair of its arms. At the center of the cross, was set a white dove descending (i.e., with its wings and head pointing downward) surrounded by green flames. The back of this cross worn by the knights was the same as the front except with the medallion of the Order of Saint Michael at the center rather than the dove and flames (those of ecclesiastical members were the same on the back as on the front). During the ceremonies, the cross of officers and commanders officers was attached to a collar of links of gold fleur-de-lis alternating with links consisting of a white enameled letter H (the first initial of name of the founder) crowned with a gold French royal crown, with identical crowns on either side of it or alternately with a trophy of weapons. Each of these links was surrounded with red enamel flames forming a square around it. More generally, the cross was suspended from a large ribbon of color moirée blue sky, hence the nickname cordon bleu the knights wore.
 For the ceremonies of the Order and when the knights of the Order made their Communion, the knights wore a long black velvet mantle sprinkled with embroidered gold and red flames and with a representation of the collar round its edges embroidered in gold, red and silver. Like the royal mantle, this mantle opened on the right side and just as an ermine shoulder cape covered the top of the royal mantle, a shoulder cape of pale green velvet with the same embroidery but smaller was worn over this mantle and formed the upper part of it. Both the mantle proper and the shoulder cape were lined with a yellowish orange satin. The mantle was worn over a white coat (with the star of the Order embroidered on the left breast), waistcoat and puffed hose, heavily embroidered with silver. A black hat with a white plume completed the dress. The star of the Order had the same design as the front of the badge, but embroidered in silver (later a medal star in silver was used) on both the knights' coats and their vests.

Only in documents relating to the Order of the Holy Spirit was white wax used for this royal seal.
