As-Suada Mosque (Arabic مسجد السعداء) or better known as As-Suada Baangkat Mosque (Arabic: مسجد السعودة بانجكات) is an old historic mosque located in Hulu Sungai Selatan Regency, East Kalimantan Province, Indonesia. This mosque was originally built in 1908, on the orders of two preachers, namely Sheikh Haji Abbas who was born in Dalam Pagar village, Martapura and Sheikh Haji Muhammad Said who was born in Amawang Village, Kandangan.

The architecture of this mosque building generally shows the application of the design concept of traditional South Kalimantan houses built on poles (houses on stilts). Then this mosque was better known by the public as Baangkat because it had a unique floor which was supported by ironwood sticks as supports so that it seemed to be lifted.
