Carl Wilhelm Moritz (1810–1855) was a German musical instrument builder.
On 8 May 1838, a concert was given to celebrate a visit to Berlin by the Tsar Nicholas I of Russia, which featured over 1,000 musicians and 200 drummers, and used Moritz's drums.
Original timpani and drums built by Moritz are still kept in museums today.
Carl Wilhelm Moritz also invented a number of new wind instruments, as his father.
After his death, his son Carl Albert Moritz continued the family business of instrument building, supplying Richard Wagner with instruments such as the bass trumpet, bass trombone and the construction of a "waldhorn tuba", the so-called Wagner tuba for performances of Der Ring des Nibelungen.
