Robert Heger (19 August 1886 – 14 January 1978) was a prominent German conductor and composer, born in Strasbourg, Alsace-Lorraine. He received his musical education at the Conservatory of Strasbourg under Franz Stockhausen, in Zurich under Lothar Kempter, and in Munich under Max von Schillings. Heger began his conducting career in Strasbourg and made his debut in Ulm around 1908 or 1909. He held positions in Barmen, the Vienna Volksoper, and Nuremberg, where he also conducted Philharmonic concerts.

Heger had a significant career in Munich and Vienna, recording Goldmark's Rustic Wedding Symphony with the Vienna Philharmonic. He conducted the world premiere of Maurice Ravel's Piano Concerto for the Left Hand with the Vienna Symphony Orchestra in 1932. In 1937, he joined the Nazi Party and conducted one of the last concerts of the Berlin Philharmonic in April 1945. Heger also worked at the Royal Opera House, Covent Garden, from 1925 to 1935 and returned in 1953 to conduct Richard Strauss's opera Capriccio.

As a composer, Heger wrote four operas, including "The Jewess of Worms" and "A Festival at Haverslev," as well as orchestral and choral works. He was awarded several honors, including the Grand Merit Cross of the Federal Republic of Germany in 1956 and the Bavarian Order of Merit in 1959. Heger passed away in Munich at the age of 91.
