Friedrich Robert Volkmann, (Hungarian: Volkmann Róbert), (6 April 1815, Lommatzsch bei Meißen – 30 October 1883, Budapest) was a German composer.
Robert Volkmann was born in Lommatzsch, Saxony, Germany. His father, a music director for a church, trained him in music to prepare him as a successor. Thus Volkmann learned to play the organ and the piano with his father, studied violin and cello with Friebel, and by age 12 he was playing the cello part in string quartets by Haydn, Mozart and Beethoven. In 1832 he entered the Freiberg Gymnasium for the purpose of becoming a teacher. There he studied music with August Ferdinand Anacker, who encouraged him to devote himself to music more fully. From there he went on to Leipzig in 1836 to study with Carl Ferdinand Becker. In Leipzig he met Robert Schumann, who encouraged him in his studies. They met again several times after that.
When he finished his studies, he began working as voice teacher at a music school in Prague. He did not stay there long, and in 1841 he moved to Budapest, where he was employed as a piano teacher and a reporter for the Allgemeine Wiener Musik-Zeitung.
After a short period of freelance work, he became the choirmaster and organist of a Reform synagogue in 1848. He composed in virtual obscurity until 1852, when his Piano Trio in B-flat minor caught the ears of Franz Liszt and Hans von Bülow, who proceeded to play it several times all over Europe. In 1854 Volkmann moved to Vienna, only to return to Budapest in 1858.
Thanks to the publisher Gustav Heckenast, who in 1857 bought the rights to publish all Volkmann's works in exchange for regular income regardless of sales, Volkmann was able to fully dedicate himself to composition, until Heckenast closed down his Budapest publishing house in the early 1870s.
