Masters W90 marathon world record progression is the progression of world record improvements of the marathon W90 division of Masters athletics. Records must be set in properly conducted, official competitions under the standing IAAF rules unless modified by World Masters Athletics. The W90 division consists of female athletes who have reached the age of 90 but have not yet reached the age of 95, so exactly from their 90th birthday to the day before their 95th birthday. Marathon running is not normally seeded into age divisions so all of these records were set in marathon races open to most other age groups.
