The Order of the Union (Dutch: Orde van de Unie) was a chivalric order established in 1806 by Louis Bonaparte, younger brother of Napoleon I, for the Kingdom of Holland.

The order was abolished in 1811 when the French Empire absorbed the Kingdom of Holland.

Louis Napoleon was highly active despite the short length of his reign and so there were six variants of the order, though these all had more or less the same form, rules and decorations and the different names were all for more or less the same order – the orders have been described by authors such as Mr. Otto Schutte [nl], Jan Albertus van Zelm van Eldik [nl], George Sanders, P.J.

They write that the order established in 1806 died out at the same time as the Kingdom of Holland.

Like the other Bonapartes, he wanted to add the luster of pomp and knighthood to his reign.
