The victory made Sweden the first country in 42 years to win both cross country relays at the same games.
Swedish anchorman Marcus Hellner was able to enjoy a victorious run into the finish, waving the Swedish flag attached to one of his ski poles, and crossing the line in a total time of 1hr 28min 42sec. His win was wildly celebrated by team-mates Lars Nelson, Daniel Richardsson and Johan Olsson.
Norway's fearsome team leader Petter Northug cut a sad and angry figure on the final leg, as his medal-less Olympics continued with just fourth place.
After also missing out on the medals in the women's relay on Saturday won by Sweden, Norway's waxing team appear to have had major problems preparing their athletes' skis for the soft Sochi snow.
The latest victory means that the Swedish team have clocked up nine medals so far; two golds, five silvers and two bronzes during the Winter Olympics which wrap up on February 23rd.
