Dobre Miasto (Polish: [ˈdɔbrɛ ˈmjastɔ]; German: Guttstadt [ˈɡʊt.ʃtat] ⓘ; literally Good City) is a town in Poland, in the Warmian-Masurian Voivodeship with 9,857 inhabitants as of December 2021.

It is also the seat of Dobre Miasto Commune which consists of the main town and 21 village administrative divisions, with a total population of 16,014.

The name of the town was spelled in different ways: Guddestat, Godenstat, Gudinstat, Gutberg, Gutenstat, Guthenstadt, Guthinstadt.

In 1347 a Collegiate Chapter was transferred here from Głotowo (Glotau), which event was of great importance for further development of Guttstadt.

In the peace treaty signed in Toruń in 1466, Warmia and Dobre Miasto were finally renounced by the Teutonic Knights and recognized as part of Poland.

In the Battle of Guttstadt-Deppen on 5 and 6 June 1807, the Russian army under General Levin August, Count von Bennigsen attacked Marshal Michel Ney's French corps.

Though badly outnumbered, Ney conducted an effective rear-guard action and escaped to the southwest across the Pasłęka River with most of his troops.

The Collegiate chapter was dissolved and its properties were parcelled out on the strength of the edict issued by King Frederick William III of Prussia on 5 October 1810.
