The Bangkok Opera is an opera company founded in 2001 as a production company to mount Madana, the first full-length grand opera by a Thai composer. This production featured in the title role the American soprano Stacey Tappan.
In 2002, under artistic director Somtow Sucharitkul, the Bangkok Opera began a series of productions with Purcell's Dido and Aeneas, moving onto larger-scale works such as Mae Naak, The Magic Flute, and Turandot.
At the end of 2005 the Bangkok Opera declared its first "complete" season and also started a five-year project to perform the complete Wagner's Ring Cycle in Bangkok. Its resident orchestra is the Siam Philharmonic Orchestra and its resident chorus is the Orpheus Choir of Bangkok. The opera company performs regularly at the Thailand Cultural Centre.
