Josef Benda, also Joseph Benda (baptized 7 May 1724 in Benátky nad Jizerou – died 22 February 1804 in Berlin), was a Bohemian violinist and composer active in Germany.
Joseph Benda was born in Benátky nad Jizerou, the son of a weaver Jan Jiří Benda and his wife Dorota Brixi, daughter of the village cantor from Slasko and member of the large Czech musical family. Five of Joseph's siblings achieved success as musicians; older brothers František, Jan Jiří and Jiří Antonín as violinist composers, and younger sister Anna Franziska as an operatic soprano.
In 1742, during the First Silesian War, Joseph was presented before Frederick the Great, who was stationed at his winter quarters at Schloss Lissa. Upon hearing the 18-year-old Joseph, the King immediately sent him to Potsdam where he was to finalise his training as a violinist with his brother František, who was already a violinist in Frederick's Hofkapelle along with Jan Jiří. Benda's remaining family in Benátky nad Jizerou, who, suffered religious persecution at the hands of the Austrian Hapsburgs, were also invited by Frederick to take up residence in Potsdam. Joseph's parents, along with their children Jan Jiří, Anna Franziska and Viktor settled in the Bohemian quarter of Potsdam called Nowawes (now Babelsberg) where his father and brother Viktor opened a weaving mill. Later that year, Joseph had already achieved a position in Frederick's Hofkapelle.
The English music journalist Charles Burney recorded two meetings with Joseph Benda in 1775. On the first occasion, on 29 September, Joseph performed a "pleasing solo, composed by his brother, which he executed with great neatness and delicacy". With the ailing health of his older brother František, Joseph became his amanuensis and assistant concert master. He succeeded his brother as concert master after his death in 1786.
