Antal Hekler (1 February 1882 – 3 March 1940) was a Hungarian/German classical archaeologist and art historian.

[1] He wrote his doctoral thesis in political science in 1903 and then studied classical archaeology in Munich under Adolf Furtwängler, where he wrote his second doctoral thesis, before he returned to his birthplace Budapest, where he first worked at the city's national museum and later held a chair for Christian archaeology and history of art at the Faculty of Sciences of the University of Budapest.

At Hekler's instigation the Budapest Museum of Fine Arts purchased 135 Greek, Roman and Italian sculptures from the Munich collection of Paul Arndt in 1908.

[2] Anna Zádor studied art history under Hekler at Pázmány Péter University (now called ELTE) starting 1922.

After graduating in 1926, she continued working under Hekler until 1936, from which time she fell under persecution as a Jew.
