Tori Amos (born Myra Ellen Amos on August 22, 1963) is a ten-time Grammy Award-nominated American pianist and singer-songwriter of dual British and American citizenship. She is married to English sound engineer Mark Hawley, with whom she has one child, Natashya "Tash" Lórien Hawley, born on September 5, 2000.

Amos was at the forefront of a number of female singer-songwriters in the early 1990s and was noteworthy early in her career as one of the few alternative rock performers to use a piano as her primary instrument. She is known for her emotionally intense songs that cover a wide range of subjects including sexuality, religion and personal tragedy. Some of her charting singles include "Crucify", "Silent All These Years", "Cornflake Girl", "Caught a Lite Sneeze", "Professional Widow", "Spark", and "A Sorta Fairytale".

Despite having little success on the charts, Amos is credited (along with Tracy Chapman) with launching the female singer-songwriter movement of the 1990s, has a large cult following, and has sold 12 million records worldwide as of 2005. Having a history of making eccentric and at times ribald comments during concerts and interviews, she has earned a reputation for being highly idiosyncratic. As a social commentator and sometimes activist, some of the topics she has been most vocal about include feminism, religion, and sexuality.
