Mary Ann Rhodes (née Dormer; 12 August 1882 – 3 March 1998) was a Canadian supercentenarian who, at the time of her death, was the third oldest person in the world, and second oldest person in Canada. Despite reaching the age of 115, Rhodes never became the oldest living person in Canada, or even Ontario, due to Marie-Louise Meilleur, who passed away one month after Rhodes, at the age of 117. Rhodes was statistically old enough to be the world's oldest person in an average year. Due to being in "second place," Mary Ann Rhodes was never in the major-media limelight, having been featured only in local media coverage.
