Eberhard Zacharias Munck af Rosenschöld, (3 August 1775 – 18 May 1840) was a Swedish physician and smallpox vaccine pioneer in Sweden.

He was influenced by his grandfather's career in medicine, enrolling as a student at Lund University in 1786; at the age of 15 he published a thesis, De rheumatismo acuto (1790), which was publicly defended under professor Johan Henric Engelhart [sv].

After being ennobled in 1799 along with his father's other children under the name Munck af Rosenschöld, he attended the 1800 Riksdag of the Estates in Norrköping, where he openly belonged to the opposition.

He also participated in the following Riksdags with great interest, usually as a member of the constitutional committee, and always remained faithful to his liberal ideas, "demonstrating the compatibility of an honest Jacobinism in opinion with the strictest obedience to the law in conduct".

As a person, he has been described as "highly original in speech, endeavors and deeds, somewhat rough and repulsive in his dealings, but basically good-natured and benevolent; he was no stranger to sacrifice and renunciation".
