Hermann Hummel (22 June 1876 – 13 September 1952) was a German chemist and politician in the Republic of Baden.

He studied astronomy, chemistry, mathematics and philosophy at the universities of Heidelberg, Freiburg im Breisgau, and Strasbourg.

By 1930, Hummel was the sole shareholder of Imprimatur GmbH and tried to financially support the opposition newspaper Frankfurter Zeitung against the propaganda machine of the Nazi Party and Joseph Goebbels.

In 1939, he emigrated to the United States, but he returned to Germany in 1951 and settled down in the Rhineland, where he lived until his death in Krefeld the following year at the age of 78.

Upon the proclamation of the Republic of Baden in 1918, Hummel first served as Deputy Minister for Military Affairs.
