Sala Daeng (Thai: ศาลาแดง, pronounced [sǎːlāː dɛ̄ːŋ]) is the name of the intersection and neighbourhood at the beginning of Si Lom Road in Bangkok, Thailand. It is located within Pathum Wan District, next to its border with Bang Rak, where Si Lom meets Rama IV and Ratchadamri Roads. The Thai–Japan Flyover Bridge, constructed in 1992, passes over Sala Daeng intersection, as well as the westward Henri Dunant and Sam Yan intersections, along Rama IV Road. A small street, known as Sala Daeng Road, branches off Si Lom Road (near the intersection) and connects to the parallel Sathon Road.
The intersection area is served by the Sala Daeng Station of the BTS skytrain's Silom Line and the Si Lom Station of the underground MRT's Blue Line, forming one of the two systems' three interchanges and a gateway into the main business district of Si Lom Road, which begins here. On the corners of the intersection are Lumphini Park, King Chulalongkorn Memorial Hospital and the Dusit Thani Hotel.
