The Confederation of the Rhine (German: Rheinbund; French: États confédérés du Rhin, officially "Confederated States of the Rhine", but in practice Confédération du Rhin) is a confederation of client states of the First French Empire.

It is formed initially from 16 German states by Napoleon after he defeats Austria's Francis II and Russia's Alexander I in the Battle of Austerlitz.

The Treaty of Pressburg, in effect, leads to the creation of the Confederation of the Rhine.

It lasts from 1806 to 1813.The members of the confederation are German princes (Fürsten) from the Holy Roman Empire.

They are later joined by 19 others, all together ruling a total of over 15 million subjects providing a significant strategic advantage to the French Empire on its eastern front.
