Joseph Paul Johannes Hoch (3 May 1815 – 19 September 1874) was a German lawyer and benefactor.
His father, the lawyer Johann Peter Hieronymus Hoch (1779 – 1831), was a magistrate and senator who, in 1829, became mayor of the Free City of Frankfurt.
His mother, the Swiss-born Ottilie von Sodenstern, was also the child of a magistrate and senator.
He decided early on, with banker Johann Friedrich Städel as his model, to bequeath enough money to his city to found an institute for education in the arts.
In his testament of 21 paragraphs, he left the Conservatory Foundation approximately one million German gold marks.
