Denmark are making their second Olympic appearance in the 4x100m relay in Tokyo, having first appeared in the event at the 1948 Games in London. They qualified for Tokyo after making the final at the 2021 World Relays, where they were the eighth and last team to progress from the heats. They went on to finish the World Relays final as the slowest of the six teams that posted an official result in the race.
At the world championships the Danish team have made two appearances, in 1983 and 2019, and failed to make the final on both occasions.
