Masters W55 marathon world record progression is the progression of world record improvements of the marathon W55 division of Masters athletics. Records must be set in properly conducted, official competitions under the standing IAAF rules unless modified by World Masters Athletics. <section begin=W55MARATHON /> The W55 division consists of female athletes who have reached the age of 55 but have not yet reached the age of 60, from their 55th birthday to the day before their 60th birthday. Age divisions are not normally seeded in Marathon running, so all of these records were set in a marathon open to most other age groups.
