Stockholm City Hall is the building of the Municipal Council for the City of Stockholm in Sweden. It stands on the eastern tip of Kungsholmen island, next to Riddarfjärden's northern shore and facing the islands of Riddarholmen and Södermalm. It houses offices and conference rooms as well as ceremonial halls, and the luxury restaurant Stadshuskällaren. It is the venue of the Nobel Prize banquet and is one of Stockholm's major tourist attractions.

The site, adjacent to Stadshusbron, being bordered by the streets of Hantverkargatan and Norr Mälarstrand to the north and west, and the shore of Riddarfjärden to the south and east, allowed for a spacious layout. The building follows a roughly rectangular ground plan. It is built around two open spaces, a piazza called Borgargården on the eastern side, and the Blue Hall (Blå hallen) to the west.

The Blue Hall, with its straight walls and arcades, incorporates elements of a representative courtyard. Its walls are in fact without blue decorations, but it has kept its name after Östberg's original design. It is known as the dining hall used for the banquet held after the annual Nobel Prize award ceremony. The organ in the Blue Hall is with its 10,270 pipes the largest in Scandinavia. Above the Blue Hall lies the Golden Hall (Gyllene Salen), named after the decorative mosaics made of more than 18 million tiles. The mosaics make use of motifs from Swedish history. They were executed by the Berlin, Germany, firm of Puhl & Wagner (Gottfried Heinersdorff), after nine years of negotiations by Gottfried Heinersdorff (1883-1941) for the commission.

The southeast corner of the building, immediately adjacent to the shore, is marked by a monumental tower crowned by the Three Crowns, an old national symbol for Sweden. The tower is 106 metres high and is accessible by an elevator or by a stair of 365 steps. The eastern side of its base is decorated with a gold-plated cenotaph of Birger Jarl.
