Santa Fe Opera (SFO) is an American opera company, located 7 miles (11 km) north of Santa Fe, New Mexico. After creating the Opera Association of New Mexico in 1956, its founding director, John Crosby, oversaw the building of the first opera house on a newly acquired former guest ranch of 199 acres (0.81 km2). The company has presented operas each summer festival season since July 1957, and is internationally known for introducing new operas as well as for its productions of the standard operatic repertoire. Five operas are presented each season during the summer.
