Shanghai Opera House (; Shanghainese: Zånhae Gujihyu) is the official government-funded western-style opera company of Shanghai, China, and the resident opera company at the new Shanghai Grand Theatre (上海大剧院 "Shanghai Da Juyuan").
 Although the term "Opera House" is often applied to the building, both in English and Chinese texts, officially the building is not an opera house and the term "Shanghai Opera House" properly applies only to the performing company, not the building, as is also true for its senior sister company, the China National Opera House (CNOH) in Beijing.
 The reason for the distinction is found in that the Chinese character "Yuan" (院) applies primarily to a school or institute or dramatic troupe rather than the building in which a school, institute or dramatic company resides.

The Peabody Opera House (formerly known as the Kiel Opera House) is a civic performing arts building located in St. Louis, Missouri.
 Founded as the Kiel Opera House, it opened in 1934 and operated until 1991, when it and the adjacent Kiel Auditorium were closed so the auditorium could be demolished and replaced by the Scottrade Center.
 When the auditorium was slated for demolition, the owners of the complex promised to rehabilitate the opera house as well.
 The owners, however, never renovated the building, instead claiming that they had fulfilled their financial obligations.
 In June 2009, the St. Louis Board of Aldermen voted 25–1 to subsidize the renovation and reopening of the Opera House under the direction of its new owners, Sports Capital Partners.
 The subsidies were funded by municipal bonds and state/federal historic tax credits.
 On July 12, 2010, it was announced that the name of the opera house would be changed to the Peabody Opera House, named after the company Peabody Energy.
 The renovation lasted for fourteen months and included the construction of a new entrance for the building.
