Dolores Mary Eileen O'Riordan (/oʊˈrɪərdən/ oh-REER-dən; 6 September 1971 – 15 January 2018) was an Irish musician who was the lead vocalist and lyricist of the alternative rock band The Cranberries. One of the most recognizable voices in rock in the 1990s, she was known for her lilting mezzo-soprano voice, signature yodel, emphasized use of keening, and strong Limerick accent.

O'Riordan was born in County Limerick, Ireland, to a Catholic working-class family. She began to perform as a soloist in her church choir before leaving secondary school to join the Cranberries in 1990. The band released the number-one Everybody Else Is Doing It, So Why Can't We? (1993), No Need to Argue (1994), To the Faithful Departed (1996), and Bury the Hatchet (1999). The Cranberries released their fifth album, Wake Up and Smell the Coffee (2001), before going on a six-year hiatus starting in 2003. During this time, she released two solo studio albums: Are You Listening? (2007) and No Baggage (2009). The Cranberries reunited in 2009,[3] released Roses (2012) and went on a world tour. Her other activities include appearing as a judge on RTÉ's The Voice of Ireland (2013–2014) and recording material with the trio D.A.R.K. (2014). The Cranberries' seventh album, Something Else (2017), was the last to be released during her lifetime.
