Spencer Proffer (born Salek Profesorski, December 25, 1948) is an American media and record producer. He is the CEO of Meteor 17, a convergence media production company based in Los Angeles, California, United States. Proffer produced the first heavy metal record, Quiet Riot's Metal Health, to reach the top of the pop charts, selling six million albums. His Children of the Sun collaboration with Billy Thorpe spawned an animated laser choreography of an album in planetariums across North America. Proffer has produced and arranged over 200 albums, many of which have achieved gold and platinum-selling status, produced or executive-produced 17 films as well as supervised and produced music for 135 films and television.

Proffer co-produced a charitable concert and media event with Doc McGhee and Quincy Jones in 2005, for over 44,000 Marines and their families, headlined by Beyoncé Knowles, Destiny's Child and Kiss, hosted by Cedric the Entertainer. In 2012, he donated 25 scholarships to youth across North America to attend Space Camp in Huntsville, Alabama.

In 2016, he completed production of Chasing Trane, The John Coltrane Documentary.

Proffer was born in Munich, Germany, and immigrated to the United States in 1954 at the age of six. He grew up in Los Angeles, California. He attended Fairfax High School. In 1967, he co-wrote "Picture Postcard", recorded by Gary Lewis & the Playboys. By the time he was 21, he had 18 songs recorded as a songwriter. After college, he secured recording contracts for various recording groups for which he was the bandleader (Dunhill, MGM, and CBS).

Proffer graduated with a Bachelor of Arts degree in Political Science from UCLA at the age of 20 and enrolled at Loyola University School of Law. He was an Executive Editor of the school's Law Review and a member of the St. Thomas More Law Honor Society. He wrote songs for the animated The Hardy Boys ABC television series and performed nights and weekends with his band, Proffer, Marmelzat and Reed (PMR).

While in law school, he attracted the attention of Clive Davis, then CEO of CBS Records, and the group was signed to a recording contract on Columbia Records. After graduating law school in 1972 at 23, he accepted a position to work for Davis at CBS and moved to New York. He left CBS shortly after Davis' departure, to become National Executive Director and Head of Worldwide A+R at United Artists Records. While at UA, Proffer produced and co-produced a number of worldwide hit records ranging from Tina Turner's Acid Queen, to the No. 1 hit "One Man Woman" by Paul Anka and Odia Coates.

Upon Transamerica's sale of United Artists in 1977, Proffer ventured on his own as an independent record producer, songwriter and arranger. He launched the Pasha Music Corporation out of a studio apartment and within a year constructed a deal with David Geffen's Elektra/Asylum Records to produce and arrange I've Got Time , the fourth solo album from Hollies lead singer, Allan Clarke.

In 1977, he met Australian guitarist and singer Billy Thorpe. Proffer and Thorpe formed a friendship and partnership and would collaborate on four albums. The first was Children Of The Sun. The album became a hit in America, and spawned an animated, laser choreography of a music album in Griffith Observatory planetarium which Proffer produced. Proffer and Thorpe had planned to produce a full-length feature film based upon the Children Of The Sun saga. However Capricorn Records, distributed by Polygram at that time, filed a Chapter 11 bankruptcy, and records were no longer available to be purchased anywhere in the country for a period of two years. Subsequently, Proffer remixed and re-released this album on his own Pasha/CBS label, 10 years later.
