Teglholmen (English: The Tiles Islet) is a peninsula in the South Harbour of Copenhagen, Denmark, located between Sluseholmen and Enghave Brygge. As part of the Southern Docklands of the Port of Copenhagen, the area used to house. While some industry activities remain in the area, but since most industry left the area, starting in the 1970s, it has undergone massive redevelopment, though some industrial activities remain, most notably MAN B&W Diesel's motor development plant. Today the area houses both a considerable number of Danish and regional headquarters of multinational companies and residential developments.

Teglholmen takes its name from a tile works whch established in the area in 1871, for many years supplying particularly Vesterbro with tiles. Around World War I, the tile works closed and the extensive clay pit was turned into a new harbour basin by connecting it to the main harbour, forming what is today known as Teglværkshavnen, separating Teglholmen from Sluseholmen. The next generation of companies to establish in the area were shipyards, foundries and a car assembly plant.
