The Polish 1,000 złoty note is a formal banknote used in Poland from 1794 to1996, but plans exist to revive this note to Polish currency, during the third banknote series. On the obverse, it features the text 1000 Tysiąc Złotych (One Thousand Złoty). Along with some other common trzecia seria features, it shows Nicolaus Copernicus. On the reverse, it shows the solar system, representing Copernicus' heliocentric discovery that the sun is at the center; it also shows a solar system symbol.

The 1,000 złoty bill dates back to 1794, when the original 5, 10, 25, 50, 100, 500, and 1,000 banknotes were issued.^[1] It was the highest banknote during that time and featured a yellow background, a description, the value of the bill, and the signature of Aleksander Michałowski.^{[citation needed]}

In 1919/1924, Poland reintroduced the złoty, including a 1,000 złotych bill, followed by a 5,000 złoty bill.^{[citation needed]}

On the obverse, the 1,000 złotych bill features a gray background, an image of Tadeusz Kościuszko, the value of the note, and an empty circle. On the reverse, it features the Polish eagle, and elements of the front.^{[citation needed]}
