Johann Christian Innocenz Bonaventura Cannabich (bapt. 28 December 1731 in Mannheim – 20 January 1798 in Frankfurt am Main), was a German violinist, composer, and Kapellmeister of the Classical era. A composer of some 200 works, he continued the legacy of Johann Stamitz and helped turn the Mannheim orchestra into what Charles Burney described as "the most complete and best disciplined in Europe.". The orchestra was particularly noted for the carefully graduated crescendos and diminuendos characteristic of the Mannheim school. Together with Stamitz and the other composers of the Mannheim court, he helped develop the orchestral texture that paved the way for the orchestral treatment of the First Viennese School.
