Herbert Barkan Newberg (1937–1992), an American attorney, was considered one of the leading class action experts in the country.

Kurt Heine of the Philadelphia Daily News wrote,His growing fame in the field of class-action litigation made him a courtroom star.

Lawyers across the country sought his testimony in class-action cases on matters ranging from civil rights and welfare to employment discrimination.

He represented thousands of women suffering health problems from the Dalkon Shield intra-uterine device, was working on behalf of about 35,000 operators of schools against asbestos manufacturers and helped force the cleanup of the Exxon Valdez oil spill in Alaska.
