Karl Klamroth (1828–1912) was a Russian violinist of German descent. He was born in Thuringia and studied with Karol Lipinski. He was the father of the painter Anton Klamroth.
From 1851 to 1901, Klamroth lived and worked in Moscow. He taught in his own music classes and, from 1863 to 1865, taught at the classes of the Moscow branch of the Imperial Russian Musical Society, the future Moscow Conservatory. He later resumed private teaching; his pupils included Georgy Dulov.
Between 1856 and 1900, Klamroth played in the Bolshoi Theatre orchestra, serving as concertmaster in his final years. Before returning to Germany in 1901, he gave a final solo violin performance in La Traviata and received an enthusiastic farewell ovation from the theatre audience.
Klamroth also wrote a number of chamber works, including the 1851 piano-duet waltz collection Farewell to the Homeland, as well as works for violin and string quartet.
