Rataje [raˈtajɛ] is a village in the administrative district of Gmina Pyzdry, within Września County, Greater Poland Voivodeship, in west-central Poland.

In 1807 it was regained by Poles and included within the newly established, however short-lived Duchy of Warsaw.

Following the duchy's dissolution in 1815, it fell to the Russian Partition of Poland.

On April 28, 1863, a Polish insurgent unit left Rataje to fight in the Battle of Pyzdry nearby.

Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the village was occupied by Germany until 1945.
