Steve W. "Silk" Hurley (born November 9, 1962), also known as J. M. Silk (for "Jack Master Silk"), is an American club DJ, house music producer, and songwriter.

From 1985 to 1988, he had four top-10 singles on the US Dance chart, including the number-one hit "I Can't Turn Around", all released in collaboration with Keith Nunnally as J. M. Silk. With "Jack Your Body" (number 25 on the U.S. Billboard Hot Dance Music/Club Play), he topped the UK Singles Chart in January 1987 as a solo artist, while one of his later compositions, "Work It Out" from 1989, brought him his fifth top-10 record on the US Dance chart (at number three). To date, Hurley's last charting single is "The Word Is Love (Say the Word)", also known as "Silk's Anthem of Life" by The Voices of Life, which peaked at number 26 in 1997 in the UK.

Hurley is a four-time Grammy Award nominee; two times as Remixer of the Year, Non-Classical (in 1999 and 2000), and twice for Best Remixed Recording, Non-Classical (in 2002 and 2003).

Hurley studied engineering at Robert Lindblom Math & Science Academy (originally named Lindblom Technical High School) in Chicago, Illinois, and later at junior college but dropped out by 1981 to concentrate on his music career full-time.

Hurley gained worldwide fame as a DJ on the Saturday Night Live Ain't No Jive Dance Party on WBMX in Chicago in the mid 1980s. Hurley's mixing style is different than the usual radio or club house DJ (such as Tony Humphries on WRKS in the early 1990s), since his style of mixing incorporates not only beatmatching, but advanced techniques only done by hip hop DJ's or turntablists such as scratching, beat juggling, cutting, needle dropping and back spinning. He released songs under the stage name of Steve "Silk" Hurley and, with vocalist Keith Nunnally, had many hits on the Billboard Dance Club Songs chart as J. M. Silk, including "I Can't Turn Around," which hit number one in 1986.

His song "Jack Your Body" was also a hit on the UK Singles Chart, reaching number one for two weeks in January and February 1987. This was the UK's first house music chart topper, achieving the number one spot with the distinction of never having been played on BBC Radio 1 other than on chart shows. In spite of "Jack Your Body"'s success, Hurley has had no further singles (under his own name) reach the UK charts, thus condemning him to one-hit wonder status. In 1988, he released an album titled Work It Out Compilation on Atlantic Records.

Hurley also worked as a prominent remixer, re-working tracks for Madonna, Michael Jackson, CeCe Peniston, New Order, Black Box, En Vogue, Janet Jackson and Inner City.

Hurley was nominated for a Grammy Award as Remixer of the Year, Non-Classical in 1998 and 1999, and for Best Remixed Recording, Non-Classical in 2002 and 2003.
