Bernt Assar Rönnlund (3 September 1935 – 5 January 2011) was a Swedish cross-country skier. Rönnlund's biggest success was at the 1962 FIS Nordic World Ski Championships in Zakopane where he won two gold medals (15 km and 4 × 10 km) and a silver (50 km). As a result, he earned the Svenska Dagbladet Gold Medal that year for his championship successes. Rönnlund was the anchorman of the Swedish 4 × 10 km relay team at the 1964 Winter Olympics in Innsbruck, bringing the team from fourth place to victory.
