Ullna Golf Club is a golf club situated on the shore of Ullna Lake in the municipality of Österåkers kommun, north of Stockholm, Sweden. Opened in 1981, it has been consistently ranked as one of the finest courses in Sweden, and had until the mid-1990s, an unrivaled position as the best course in the Stockholm area. In the Swedish Golf Digest 2005 ranking of Swedish courses, it was ranked 11th. Ullna is famous for its beautiful setting. It is unique in its proximity to open water, with the lake coming into play on 6 of the 18 holes. In 2011  Jack Nicklaus and his team at Nicklaus Design conducted a massive renovation and redesign, and in 2013 the course re-opened with mint condition bentgrass fairways, superfast greens, intricate bright-white marble bunkers and an upgraded layout.
