Sebastian Bach (born April 3, 1968) is a Canadian heavy metal singer who achieved mainstream success as frontman of Skid Row from 1987 to 1996. Since his departure from Skid Row, he has had many television roles, acted in Broadway plays, and led a successful solo career.

Bach was born Sebastian Philip Bierk on April 3, 1968, in Freeport, Bahamas, and raised in Peterborough, Ontario, Canada. He attended nearby Lakefield College School in the same class as Michael Kulas, of the British rock group James, a year behind Felipe, Prince of Asturias and a year ahead of the comedian/actor Will Arnett. He is of Norwegian, French Canadian, and Native American descent. Bach's father was the visual artist David Bierk. He is the brother of retired NHL goaltender Zac Bierk, model/actress Heather Dylan Bierk, and Toronto-based artists Jeff, Nick, Alex, and Charles Bierk.

Skid Row initially formed in the late eighties with lead singer Matt Fallon. They began playing at various New Jersey clubs. Fallon would soon leave the band in 1987, leaving Skid Row without a singer. Bach, who had just left his previous band Madam X, was spotted singing at rock photographer Mark Weiss's wedding and the members asked him to join. He turned them down, but changed his mind after hearing the demo tapes of "Youth Gone Wild" and "18 and Life". He sent them a demo of him singing "Saved By Love." They loved it and flew him to New Jersey where they began playing gigs. Sebastian also recorded demos with Bon Jovi & Sabo's friend Jack Ponti. (The song "She's on Top" later came out on Jack Ponti Presents Vol. 1)
