Leopold Rottmann (2 October 1812, Heidelberg - 26 March 1881, Munich) was a German landscape painter.
His father, Friedrich Rottmann [de], was a painter and a Professor of Drawing, who gave him his first lessons.
He continued his studies with Jakob Wilhelm Roux and completed them with his older brother, Carl Rottmann.
Julius Mařák, a landscape painter and, later, Professor at the Academy of Fine Arts, Prague, was one of his better known non-royal students.
Although he was primarily a Naturalist, his style also shows the influence of Classically trained painters, such as Joseph Anton Koch and Friedrich Preller the Elder.
