Pieter Hubert Ries (April 1, 1802 – September 14, 1886) was a German violinist and composer.
Ries was born in Bonn, the son of Franz Anton Ries and the brother of Ferdinand Ries; after studying with his father, Hubert studied in Kassel with Louis Spohr and Moritz Hauptmann. In 1824, he became a member of the Köningstadt Theater Orchestra, and the next year entered into service at the court chapel. In 1835, he became director of the Berlin Philharmonic Society. From 1851 to 1872 he taught at the Royal Orchestra School. He had three sons, all of whom entered into music: Louis Ries (born January 30, 1830), a violinist; Adolf Ries (born December 20, 1837), a pianist; and Franz Ries (born April 7, 1846), a violinist and composer. He died in Berlin.
Among Hubert's compositions are two violin concertos, string quartets, etudes, duets, and exercise pieces. He also wrote a textbook, Violinschule (1873).
