Franz Steinfeld (Vienna, 26 March 1787 – Písek, Bohemia, 5 November 1868) was an Austrian landscape painter. He is often called "the Younger" to distinguish him from his father, also named Franz, who was a sculptor. He is remembered as one of the first painters to work in the Alps and as someone who helped give landscape painting a more Classical character, while also being among the first in the genre to adopt the Biedermeier style.
He first learned sculpting from his father, but at the suggestion of the engraver Francesco Vasanova he enrolled at the Academy of Fine Arts in Vienna, where he studied with Laurenz Janscha, Martin von Molitor and Albert Christoph Dies. In 1805 he travelled to the Rhineland and the Netherlands, where the work of Jacob van Ruisdael drew his attention. From 1815 to 1835 he was court painter to Archduke Anton Viktor. He first exhibited at the Academy in 1822, became a member the following year, and was made a professor in 1845.
As a teacher he encouraged drawing and painting outdoors from nature and asked for the academy's windows to be enlarged to bring in more light. He travelled often through Italy, Germany and Switzerland and spent an extended period in Belgium with Josef Danhauser. Besides landscapes, he also made etchings and lithographs. He died during a visit to Bohemia.
