Anton Hallmann was a German painter, draftsman and writer.

After an apprenticeship with the architect Ludwig Hellner in Hanover, Hallmann attended the academy in Munich. In 1833 he travelled through Tyrol to Italy, where he stayed in Rome until 1836, interrupted by trips to Sicily. In 1834 he joined forces with the art historian Wilhelm Schulz from Dresden to publish a work on the monuments of medieval art in southern Italy. The work did not appear in print until 1860. In 1837 Hallmann returned to Munich, but the following year he went to Petersburg, then to England and France. Returning to Rome in the spring of 1841, he painted architectural pictures in oil, including the monastery garden near Fossa Nuova.

In 1842 he published the work Kunstbestrebungen der Gegenwart. In 1843 he traveled to Rome again and completed several large oil paintings there, among which the painting A Day in Cyprus is characterized by richness of composition and opulence of the imagination. In 1844 he painted a large dilapidated villa with evening lighting for the King of Prussia. In 1845 he was one of the founders of the German Art Association in Rome. He died of malaria on his return to Germany in the same year.
