Scott Weiland (born Scott Richard Kline on October 27, 1967) is an American musician, lyricist, and vocalist, most notably known for his work with Grammy Award-winning rock band Stone Temple Pilots, and also for his five-year career with supergroup Velvet Revolver. After a five-year hiatus, the STP reunion tour kicked off at the Rock on the Range festival in May 2008. He was the frontman of Velvet Revolver during his time away from STP, but parted ways with the band on April 1, 2008. Weiland's split from Velvet Revolver also led to his departure from the side-project band Camp Freddy. Weiland's second solo album, "Happy" in Galoshes, was released on November 25, 2008. Weiland supported the record with an early 2009 tour of the United States.

Weiland is one of the most successful frontmen to emerge from the 1990's. He is well-known for his flamboyant and energetic onstage persona and for constantly changing his appearance and vocal style. Weiland's life and career have been plagued with heroin addiction, as well as several arrests. However, according to MTV News, Weiland has been free from heroin since December 5, 2002.

Weiland was born as Scott Kline in Seattle, Washington. His surname was changed after being adopted by his stepfather David Weiland at age 5. Around that time, Weiland moved to Chagrin Falls, Ohio, where he attended the Kenston School District. He moved to California as a teenager and attended Edison High School in Huntington Beach.
