Augusta Dorothea of Brunswick-Wolfenbüttel (16 December 1666 in Wolfenbüttel - 11 July 1751 at Augustenburg Castle in Arnstadt) was a daughter of the Duke Anthony Ulrich of Brunswick-Wolfenbüttel and his wife Juliane of Holstein-Norburg.
Auguste Dorothea married on 7 August 1684 in Wolfenbüttel to Count Anton Günther II of Schwarzburg-Sondershausen. He was elevated to Imperial Prince in 1697. The couple resided in Arnstadt; the marriage remained childless.
Auguste Dorothea survived her husband by 35 years. She spent her long widowhood at Augustenburg Castle in Arnstadt, building her famous dolls collection French: Mon Plaisir. These dolls were never intended as toys; they represent society in the style of a baroque Cabinet of curiosities. Augustenburg castle no longer exists; her doll collection has been moved to the New Palace in Arnstadt.
