The NYPD says the eight are wanted for questioning in the January 23 incident. Police released pictures of the suspects in the hopes that the public will help locate them.
Up to five of the eight appear to favor New York Yankee baseball caps.
The victim, Kenyatta Cotterell, was knifed in a wild brawl outside the club on West 47th Street. Another man had been charged, but a grand jury refused to indict him.
Anyone with information is asked to call police.
