Christopher Edward Martin (born March 21, 1966), better known by his stage name DJ Premier (also known as Preemo or Preem for short), is a record producer and DJ. He produced six albums as the instrumental half of the hip-hop duo Gang Starr, along with emcee Guru. DJ Premier has been labeled by many as arguably the greatest producer in hip-hop history.

Born in Houston and raised in Prairie View, Texas, he has lived in Brooklyn, New York, for much of his professional career. Despite his Southern roots, Premier became synonymous with intricate sampling and the boom-bap sounds of East Coast hip-hop in the 1990s. He has worked with some of the biggest names in hip-hop such as Biggie, Jay-Z, Nas, Snoop Dogg, Scarface, Common, Drake, Dr. Dre, and Kanye West among others. He has also worked with R&B and pop artists such as Christina Aguilera, D'Angelo, and Miguel. DJ Premier also joined another group, forming PRhyme with Royce da 5'9".
