Dennis Coles, better known by his stage name Ghostface Killah, is an American rapper and member of the Wu-Tang Clan. After the group achieved breakthrough success in the early- to mid-1990s, each member was free to pursue solo careers.

Ghostface Killah took his name from one of the characters in the 1979 kung fu film Mystery of Chessboxing.

In 2006, Ghostface teamed up with underground favorite MF DOOM for a still unreleased album entitled Swift & Changeable. MF DOOM also produced several songs for Ghostface's 2006 album Fishscale, which was once again attributed to "Ghostface Killah". The album debuted strongly, in the #4 position on the US Billboard 200 and at #2 on the R&B charts,   the rapper's most auspicious chart showing since the heyday of the Wu-Tang Clan and the release of his solo debut. The album also nearly unanimously received positive reviews. Ghostface embarked on a limited-date tour of US venues in support of the album, performing several of his concerts together with most members of the Wu-Tang Clan.

He has worked with 4Cast to produce his own action figure.   In December 2007 Ghostface appeared on Spinner.com's comedy show The DL  to do a holiday commercial for his action figure.

On December 4, 2007 Ghostface released his seventh solo studio album, The Big Doe Rehab.

In a recent interview, Ghostface Killah said that his next project is going to be an R&B album. It is going to be in the vein of the tracks he has done before with such artists as Ne-Yo and Jodeci
