Jörg (Georg) Ebert (died 1582) was a renowned German organ builder. He is first mentioned in documents from 1531 in Rothenburg ob der Tauber and later resided in Ravensburg from 1534, where he owned property. Despite being a sought-after organ builder, Ebert was known among his contemporaries for his erratic and peculiar behavior, often falling behind on his projects.

One of his most significant works was the organ in the Innsbruck Hofkirche, completed in 1555, which stands as a testament to his craftsmanship. In 1561, Emperor Ferdinand I commissioned Ebert to complete the unfinished organ in the Prague Cathedral after the previous builder, Ferdinand Pfannmüller, had passed away. Ebert continued working on this organ the following year but was unable to complete it. His notable works include organs for the Liebfrauenkirche in Ravensburg (1541), Freiburg Münster (1544-1546), and the Münster St. Nikolaus in Überlingen (1548-1550), though many of his instruments have not survived.
