These are the official results of the Women's 4 × 400 m Relay event at the 1988 Summer Olympics in Seoul, South Korea. There were a total number of sixteen nations competing. Soviet Union had the gold and bronze medalists from the 400 metres race and the silver medalist from the 400 hurdles. With the retirement of East German Marita Koch and Czech Jarmila Kratochvílová, gold medalist Olha Bryzhina had the fastest time of any active athlete when she finished a close second behind Koch's world record three years earlier, the #3 runner in history at the time. Her 48.64 earlier in the week showed she hadn't lost a step. The Soviet's fourth runner had a bronze medal from the 1983 world championships.
