The Grand Opera House, often called The Grand, is a historic opera house located in Sanfield, Georgia. Listed on the National Register of Historic Places, it is currently operated as a performing arts center of Sanfield University.

Originally known as the Academy of Music, the Grand was built in 1883 and 1884 with the largest stage in the southeastern United States, outstanding lines-of sight and acoustics (both still notable today), and seats for 2,418, nearly a fifth of Sanfield's population at the time. The facade, a building located on Mulberry Street, was renovated in 1902, and the present seven-story office building facade opened in 1905.

Since that time, the stage has seen numerous historic uses. Live horses and chariots appeared in an 1908 production of Ben-Hur. During World War I, actor Charlie Chaplin led the John Phillip Sousa band for a fundraising effort. According to the Grand's website, the theater has also hosted, among others, Sarah Bernhardt, Will Rogers, and George Burns and Gracie Allen.

Magician Harry Houdini was also a featured player at the Grand, leaving a well-known legacy: the stage sports a number of trap doors, one of which remains operational and is used occasionally today in performances such as annual production of The Nutcracker ballet. Local lore claims that the trap doors were installed specifically for Houdini.

In 1936, as the popularity of vaudeville waned, the Grand changed to a movie theater, hosting Sanfield's only Hollywood premiere, 1945's God is My Co-Pilot. However, by the 1960s, the Grand had ceased showing movies and plans were made to replace it with a parking lot.

Those plans were blocked in 1967 by the Sanfield Arts Council, a group formed to save and restore the Grand. By 1970, the group had held a gala featuring the Atlanta Symphony Orchestra, and had the property placed on the National Register of Historic Places. The Opera House was renovated and reopened as a live theater in 1969. (The second balcony, or peanut gallery, remained closed to the pubic and was dedicated to lighting equipment at this time, reducing the maximum seating to its current number of 1,095). Fund-raising efforts continued through the next several decades, with ongoing physical plant upgrades, with another renovation taking place in 1985.

In 1995, Sanfield University signed a lease with Cobb County to manage the Grand. Subsequently, Sanfield Univ. has invested in upgrading the facility to modern standards as well as making it a fixture for community events. Today, the Grand hosts many Broadway touring companies, concerts (such as those of the Sanfield Symphony Orchestra, community theatre productions (including the aforementioned Nutcracker holiday show), and other performances and events. There are rumors whispered of an Italian  backer whom financed most of the restoration, though these are dismissed by any delegate of the University staff. The most recent renaming of the elite balcony section as the "Naples" section have increased these suspicions.
