Princess Elisabeth of Stolberg-Rossla (German: Elisabeth zu Stolberg-Roßla; 23 July 1885, Roßla—16 October 1969, Eutin, Schleswig-Holstein) was the second wife of Duke Johann Albrecht of Mecklenburg, Regent of the Duchy of Brunswick.

Born into an ancient House of Stolberg, she was second daughter of Prince Botho of Stolberg-Rossla (1850-1893), son of Count Karl of Stolberg-Rossla (1822-1870) and his wife, Countess Bertha of Solms-Rödelheim and Assenheim (1824-1898).

She was married to Duke Johann Albrecht of Mecklenburg-Schwerin on 15 December 1909, a year after the death of his first wife Princess Elisabeth Sybille of Saxe-Weimar-Eisenach.

After her first husband's death in 1920, Elisabeth remarried to his half-brother, Duke Adolf Friedrich of Mecklenburg, at Ludwigslust in Grand Duchy of Mecklenburg-Schwerin.

Elisabeth died in Eutin, Schleswig-Holstein, on 16 October 1969, only two months after the death of her second husband.
