Inga Nielsen (2 June 1946 – 10 February 2008) was a Danish soprano who had an active international opera career from 1971 to 2006. A child prodigy, Nielsen performed on American radio during the 1950s, beginning at the age of six, and also released some commercial recordings of Danish folk songs and Christmas carols as a child. She began her opera career performing parts in the lyric soprano repertory and then became an admired singer of dramatic soprano roles, beginning in the late 1980s.
