Elections to the Labour Party's Shadow Cabinet took place on 24 October 1990. Under the rules then in effect, the Commons members of the Parliamentary Labour Party elected 18 members of the Official Opposition Shadow Cabinet, who were then assigned portfolios by the leader. The Commons members of the PLP separately elected the Chief Whip, and the Labour peers elected the Leader of the Opposition in the House of Lords. In addition, the Leader of the Labour Party and Deputy Leader (Neil Kinnock and Roy Hattersley, respectively) were members by virtue of those offices.
As a result of the election, Joan Lestor lost her seat in the Shadow Cabinet, and was replaced by Ann Taylor; all other members were re-elected.
† Multiple candidates tied for position.
