Josef Alois Knittel (20 April 1814, Oberbach – 23 December 1875, Freiburg im Breisgau) was an Austrian-born German sculptor.

He displayed an early talent for art, which prompted his drawing teacher, Anton Falger [de], to suggest that he be sent to Munich for further studies.

[4] He was awarded a major commission by Mayor Carl Röttinger to create four statues, depicting the seasons, for the grounds of the Freiburg railway station.

His best known work is the monument to Berthold Schwarz, the alchemist credited with inventing gunpowder, on the Freiburg town square.

Several works, including a large statue of Albert VI, Archduke of Austria, were destroyed during World War II.
