The 1991 IAAF World Women's Road Race Championships was the ninth and final edition of the annual international road running competition organised by the International Amateur Athletics Federation (IAAF). The competition was hosted by the Netherlands on 13 October 1991 in Nieuwegein and featured one race only: a 15K run for women. There were individual and team awards available, with the national team rankings being decided by the combined finishing positions of a team's top three runners. Countries with fewer than three finishers were not ranked.
