Debbie Obarski (born December 10, 1969) is an American female singer, best known as the frontwoman of the Ozzy Osbourne tribute bands The Little Dolls and Diary of a Madwoman, as well as a short stint with The Iron Maidens.

Deb Obarski was born and raised in San Jose, California, where she took up singing through her sister and grandmother, as well as in church and school choirs.

Two years later, she moved to Los Angeles, where she performed a handful of her original compositions at coffee houses.

Shortly after recording a demo of her original songs, Obarski retired from the music scene for 10 years – eventually marrying, buying a home and divorcing within that time span.

Not too long after her divorce, Obarski returned to her musical roots, singing with a heavy metal cover band part-time before joining the all-female Ozzy Osbourne tribute band The Little Dolls (named after a song from Osbourne's second album Diary of a Madman) from 2006 to 2009.
