Herbert Heyner (26 June 1882 – 18 January 1954) was a noted English baritone. Heyner appeared in a handful of operas, and a number of broadcast operas, but his stage appearances were predominantly in oratorio and songs. He sang in some notable performances of Sir Edward Elgar's oratorios under the composer's baton. He sang in Britain, France, Germany, the United States and Canada, and he sang at The Proms 59 times between 1909 and 1937, in songs and operatic arias.
Herbert Augustus Otto Heyner was born in London on 26 June 1882. He was a choirboy at St Botolph's Aldersgate, making his debut in that capacity in 1892; he was also accepted for Lincoln's Inn Chapel. He studied at Brighton House School and it was planned that he would become an actuary, but music had a greater pull on him, and he studied singing with Frederic King in London, Victor Maurel in Paris, and Karl Scheidemantel in Dresden. Maurel had believed Heyner's true range was that of a bass, but it proved to be baritone.
His first important appearance was in 1907, at the Queen's Hall. On 27 May 1911 the London Music Festival closed with a performance of Bach's St Matthew Passion, with Heyner, Gervase Elwes, Robert Radford and Agnes Nicholls, under Sir Henry Wood's baton. In 1912 he and the soprano Muriel Foster sang in a series of concerts at Queen's Hall with the London Symphony Orchestra, led by Arthur Nikisch, Willem Mengelberg and Hamilton Harty.
