Auguste Leopoldine Hedwig Countess of Rittberg (1839–1896) was a Prussian-German decorated nurse, hospital supervisor and founder of the Auxiliary Sisters Association.

With the outbreak of the Austro-Prussian War (1866) the young countess took up nursing and completed a course in the cuirassier barracks in Breslau, now Wrocław, Poland.

In appreciation for her nursing service in Hořice and Gitschin during the three-month war, she received the Order of Louise, 1st class.

Coincidentally, Rittberg had been an early advocate for an international organization such as the Red Cross to care for the sick and wounded.

In 1918, under the direction of Elsbeth von Keudell (1857–1953), the Red Cross Sisterhood of Rittberg bought the hospital and trained nurses there.
