The 1990 West Virginia Attorney General special election took place on November 6, 1990, to elect the Attorney General of West Virginia. The election was held to complete the unexpired term of Charlie Brown, who resigned in August 1989 to end a grand jury investigation against him. Incumbent Democratic Attorney General Roger W. Tompkins, who was appointed by governor Gaston Caperton, chose not to seek election to a full term.
Former Democratic State Senator Mario Palumbo won the general election unopposed, as the Republicans did not field a candidate.
