Josef Erler (9 February 1804, Brixen - 31 March 1844, Innsbruck) was a landscape painter from the Austrian Empire.
He received his first drawing lessons in Brixen from a local artist named Josef Tauber.
He returned to Brixen in 1836 and died while visiting Innsbruck, at the age of only forty.
His painting of the newly constructed Franzensfeste Fortress was acquired by Emperor Ferdinand I.
Some of his works were presented as gifts to Vincenzo Tizzani [de], the Bishop of Terni.
