Hammarbytoppen, Urban ski hill in Stockholm, Sweden.

Hammarbytoppen is an artificial hill in Björkhagen, southern Stockholm, rising 93.5 metres above sea level. Its northern slope holds four ski runs named Åre, Trysil, Vemdalen and Sälen, with a maximum vertical drop of 85 metres. The longest run is 750 metres, and the slope is served by two surface lifts.

A ski jump built by Djurgårdens IF in 1919 stood on the wooded hill, which originally reached 55 metres above sea level. A larger jump was built for the 1951 Swedish championships, and the site took the name Hammarbybacken. In 1983 the hill was raised to 87.6 metres with over 800,000 cubic metres of fill, including material from the Globen construction; the alpine facility opened in 1990.

The slopes carry names from Swedish ski resorts: Åre (red), Trysil (blue), Vemdalen and Sälen (green). Since 2016 the hill has hosted a parallel slalom World Cup; on 23 February 2016 Carl XVI Gustaf watched Wendy Holdener and Marcel Hirscher win.

The slopes run down the hill's northern side, with the longest descent 750 metres and a maximum drop of 85 metres. The four runs are named Åre, Trysil, Vemdalen and Sälen. A lift carries riders up for the Mountain Coaster, an 800-metre mono-rail sled run reaching 40 km/h.

Since 2019, large rock chambers have been blasted inside the hill for a new wastewater treatment plant serving Stockholm Vatten och Avfall's Sickla facility, part of the Henriksdal plant. The work goes on beneath the slopes while skiers and mountain bikers use the surface above.
