Douglas Lars "Doug" Fieger (August 20, 1952 - February 14, 2010) was an American singer-songwriter. He was the lead singer of the Power pop band The Knack, and co-wrote the biggest hit song of 1979, "My Sharona", with lead guitarist, Berton Averre. Fiegers father was Jewish, and his mother Norwegian. Doug was the younger brother of Detroit attorney Geoffrey Fieger who confirmed his death on Valentines Day, 2010 to The Detroit News. Doug Fieger was born and raised in the 9 Mile/Coolidge area of Oak Park, Michigan, a northern suburb of Detroit, and attended Oak Park High School. Before forming The Knack, Fieger played bass and sang lead in the group Sky (Sky (US band)), which was founded by producer Jimmy Miller (Rolling Stones, Traffic (Traffic (band)), Blind Faith) when Fieger was still in high school. Sky recorded two albums for RCA Records, in 1970 and 1971, produced by Miller with Andy Johns (Led Zeppelin). Fieger also played bass guitar in the German progressive rock band Triumvirat for a short period in 1974.

In addition to performing, Fieger also produced the Rubber City Rebels debut album for Capitol Records and another album for the Los Angeles-based band, Mystery Pop. He and Rebels drummer Brandon Matheson had been bandmates in The Sunset Bombers and had one album released on Ariola Records, before Fieger formed The Knack. The band played its initial gig at Hollywoods Whisky A Go-Go nightclub on June 1, 1978 and were discovered playing Los Angeles area nightclubs, including The Troubadour (The Troubadour (Los Angeles)) in West Hollywood. They were signed by Capitol Records in early 1979.

"My Sharona" spent six consecutive weeks at #1 on Billboards Hot 100 in 1979 and was the biggest hit of the year. Fifteen years later the track gained new interest after it was heard in the film Reality Bites. It was also featured regularly in a Saturday Night Live skit parodying Janet Reno. The follow-up hit to "My Sharona" was "Good Girls Dont (Good Girls Dont (song))" which stopped one notch short of the Top 10 - peaking at #11, while Get The Knack spent five straight weeks at #1 and eventually sold 3 million copies in the United States - 6 million globally.

Additionally, Fieger provided lead vocals on two tracks on Was (Not Was) 1983 album Born to Laugh at Tornadoes. And shortly before his death, he provided lead vocals for the track "Dirty Girl," from Bruce Kulicks 2010 album BK3 (BK3 (album)).
