Ante Šercer (1896, Požega, Kingdom of Croatia-Slavonia - 1968) was a Croatian physician.
He attended elementary school in Dubrovnik. Finishing medical studies in Graz (Austria) and Prague (Czech Republic), he soon attended the specialized courses in Othorinolaringology (otolaryngology) in Zagreb, Vienna, and again, in Prague. He started practising at the clinical hospital of the Medical Department (Medicinski fakultet) in Zagreb in 1920, and eventually became its administrator and an associate professor. Later, in 1946, he became head of the department of the othorinolaringology of the Sisters of Charity Hospital (Bolnica Sestara Milosrdnica).
Due to his efforts, and those of Eduard Miloslavić, the Medical Faculty was created in Sarajevo, Bosnia and Herzegovina, in 1944 with eight lecturers. At that time, he also advocated opening the Center for Oriental Studies there. The University of Zagreb provided 15 t of material and other equipment and books needed for 180 students in that first year. Due to that effort, when World War II ended, academician Šercer was sentenced by the newly created government of Yugoslavia to one year of forced labor and the confiscation of the property, found guilty of supporting the NDH.
