Carolina Östberg (17 May 1853 – 27 February 1924)[1] was a Swedish opera singer and singing teacher.
She was active as a concert singer before she made her debut Stora Teatern at the 1873–74 season with Louise Pyk.
When she was unexpectedly launched in the lead role of Boccaccio in Nya Teatern in 1879, "The applause never seemed to stop", and the press demanded that she be given a position at the Royal Swedish Opera.
She performed in Copenhagen (1880), Germany (1882–83), Norway (1885), and Nya Teatern in Stockholm under the name Mrs Östberg.
This was seen as the triumph of the audience over the operatic management: "The Public had had its will" over the opera, after having demanded that she be employed there for years.
