Judith Holofernes, German singer-songwriter and guitarist
Judith Holfelder-Roy (née Holfelder-von der Tann; born 12 November 1976), known by her stage name Judith Holofernes, is a German singer, guitarist, songwriter and author.

She was the lead singer of Wir sind Helden, the German pop rock band that released the song "Guten Tag" in 2002. The band received critical acclaim owing in part to Holofernes' lyrics, which are characterized by their playful use of words and use of social criticism.

After recording four albums that were chart successes in the German-speaking world, Wir sind Helden went on indefinite hiatus in 2012. Since then, Holofernes has recorded two solo albums (Ein leichtes Schwert, 2014; Ich bin das Chaos, 2017) and has also had a book of poems published (Du bellst vor dem falschen Baum, 2015).
