Bengt Lidner (March 16, 1757 – January 4, 1793) was a Swedish poet, born in Gothenburg. His opera Medea was translated to English and played in England during his lifetime, but wasn't played in Sweden until 2004. Lidner's collected works have appeared (in Swedish) in many editions, most recently in the text critical edition of Svenska Vitterhetssamfundet in four volumes, 1930-1992.
