Stolberg (pronounced Stoul-berg Stolbergⓘ) is a town (sometimes itself called 'Harz' in historical references) and a former municipality in the district of Mansfeld-Südharz, in the German State of Saxony-Anhalt, Germany.

Stolberg was established as a settlement for miners in around AD 1000, although there is evidence of mining in the area as far back as 794.

Coins were minted in Stolberg as early as the High Middle Ages, the industry reaching its heyday during the 16th century.

The town was awarded to the Kingdom of Prussia in the 1815 Congress of Vienna and Stolberg was subsequently administered by the Prussian Province of Saxony.

Until the separation of church and state in 1919 it was directly subordinate to the imperial lord (Standesherr), the Count or Prince of Stolberg-Stolberg and indirectly to the governor (Oberpräsident) of the Province of Saxony.

In early 1946, "14 youths aged from 15 to 18" (two were 19 and 20 years old) were arrested by an operational group of the Soviet Security Service, the NKWD, on allegations of being involved in Werwolf, the Nazi plan to form a commando force.

They were sentenced by a military tribunal to death (3 youths, carried out in two cases) or to lengthy terms in prison of up to 25 years.

Motorists can approach the town from the Harz Mountains to the north and the Kyffhäuser Hills to the south, leaving the A 38 motorway at the Berga junction.

These excursion services ran on weekends, once in the morning to Stolberg and once in the afternoon back towards Leipzig and Magdeburg.
