The acclaimed musician released 10 studio albums.
Song Nothing Compares 2 U was named the number one world single in 1990 by the Billboard Music Awards.
In a statement, the singer’s family said: “It is with great sadness that we announce the passing of our beloved Sinéad. Her family and friends are devastated and have requested privacy at this very difficult time.”
Ms O'Connor is survived by her three children Jake, Roisin and Yeshua. Her son Shane died last year aged 17.
Taoiseach Leo Varadkar said: “Really sorry to hear of the passing of Sinead O’Connor.
“Her music was loved around the world and her talent was unmatched and beyond compare.”
The Dublin-born singer was propelled to international stardom in 1990 with her version of Nothing Compares 2 U.
Written by Prince, Ms O’Connor made the song her own and topped the charts in countries around the world.
