Olga Yvonne Agar (28 June 1903? – fl.4 August 2017) was a supercentenarian claim from Mauritius.
Olga claims to have been born on 28 June 1903. At the age of 24, she married Alois Agar and moved to Mon Loisir, Belle Vue Maurel, where her husband worked as a mechanic. She had ten children (four girls, six boys). She never missed mass and insisted that her children should say their prayers before going to sleep. After the death of her husband, she had a lot of grief but accepted the fact that "God needs the people he loves".
At the age of 110, she was in great shape and was able to walk without the help of anyone. Twelve years prior to her claimed 113th birthday, she moved to her daughter's house in Pamplemousses. On her claimed 113th birthday, she had 23 grandchildren and several great-grandchildren. On her birthday, she said that she would like to live up to 120 years.
Agar was last known to be alive on 4 August 2017 at the claimed age of 114 years, 37 days.
