Miastko [ˈmʲastkɔ] (Kashubian: Miastkò; German: Rummelsburg), is a town in the Middle Pomerania region of northern Poland, administratively located in the Bytów County in the Pomeranian Voivodeship.

Traces of human settlement of the Pomeranian and Wielbark cultures and from ancient Roman times and Early Middle Ages were discovered during archaeological excavations in Miastko. The area became part of the emerging Polish state under its first historic ruler Mieszko I in the 10th century. Following the fragmentation of Poland, it formed part of various smaller duchies, including the Duchy of Słupsk from 1368 and Duchy of Pomerania from 1478.

From the 18th century, it was part of the Kingdom of Prussia, within which it belonged to the Province of Pomerania. During World War II, the Polish resistance conducted espionage of German activity in the town. The Germans operated three forced labour subcamps of the Stalag II-B prisoner-of-war camp in the town. In January 1945, a German-perpetrated death march of Allied prisoners-of-war from the Stalag XX-B POW camp passed through the town. On 2 March 1945, it was taken by the Red Army.

In April 1945, a Polish operation group of 22 young men arrived in the town to take over administration of the town, while the German population was largely still present. The Potsdam Agreement confirmed preliminary Polish administration of the region and the native German populace was expelled. According to German reports, in January 1947, Germans to be expelled were collected and had to camp in ruined houses at min 25 degrees minus. British authorities of occupied Germany did not receive the expellees, whoh were interned until March 1947 in various internment camps. Of 2500 Germans of a transport scheduled for January 4, 1947, 500 were not to survive the expulsion.

Until 1975, Miastko was a county seat within the Koszalin Voivodeship, and from 1975 to 1998 it was administratively located in the Słupsk Voivodeship.

In 2012 a monument dedicated to the Polish Nation was unveiled in the town park.
