The Spanish Colonial Revival architecture (Spanish: Arquitectura neocolonial española), often known simply as Spanish Revival, is a term used to encompass a number of revivalist architectural styles based in both Spanish colonial architecture and Spanish architecture in general. These styles flourished throughout the Americas, especially in former Spanish colonies, from California to Argentina.

In the United States, the earliest use of this style was in Florida, Texas, and California. St. Augustine, Florida was founded on September 8, 1565, by Spanish admiral Pedro Menéndez de Avilés, Florida's first governor. The city had served as the capital of Florida for over 250 years when Spain ceded Florida to the United States in 1819. By the late 1880s, St. Augustine was being developed by Henry M. Flagler as a winter resort for wealthy northern families. He built two grand hotels in the Mediterranean Revival and Spanish Revival styles: the Ponce de Leon Hotel (Carrère and Hastings, 1882) and the Alcazar Hotel (Carrère and Hastings, 1887). These influenced the development of the Spanish Colonial Revival style. A few years later, at the Panama–California Exposition of 1915 in San Diego, highlighting the work of architect Bertram Goodhue, Spanish Colonial Revival was given further national exposure. The McNay Art Museum, founded in 1954 in San Antonio, is the first modern art museum in Texas was built in Spanish Colonial Architecture style. Embraced principally in Florida, Texas, and California, the Spanish Colonial Revival movement enjoyed its greatest popularity between 1915 and 1931.

In Mexico, the Spanish Colonial Revival in architecture was tied to the nationalist movement in the arts encouraged by the post–Mexican Revolution government. The Mexican style was primarily influenced by the Baroque architecture of central New Spain, in contrast to the U.S. style which was primarily influenced by the northern missions of New Spain. Subsequently, the U.S. interpretation saw popularity in Mexico and was locally termed colonial californiano.

Modern-day tract home design in Southern California and Florida largely descends from the early movement. The iconic terracotta shingles and stucco walls have been standard design of new construction in these regions from the 1970s to present.

The antecedents of the Spanish Colonial Revival Style in the United States can be traced to the Mediterranean Revival architectural style. In St. Augustine, Florida, a former Spanish colony, a winter playground was developing for wealthy people from northern cities in the United States. Three architects from New York City John Carrère and Thomas Hastings of Carrère and Hastings and Bostonian Franklin W. Smith, designed grand, elaborately detailed hotels in the Mediterranean Revival and Spanish Revival styles in the 1880s. With the construction of the Ponce de Leon Hotel (designed by Carrère and Hastings, 1882), the Alcazar Hotel (Carrère and Hastings, 1887), and the Casa Monica Hotel (later the Hotel Cordova) built by Franklin W. Smith in 1888, Spanish-influenced architecture spread to several other parts of Florida. These three hotels were influenced not only by the centuries-old buildings remaining from the period Spanish rule in St. Augustine but also by The Old City House, constructed in 1873 and still standing, an excellent example of early Spanish Colonial Revival architecture.

The possibilities of the Spanish Colonial Revival Style were brought to the attention of architects attending late 19th and early 20th centuries international expositions. For example, California's Mission Revival style Pavilion in white stucco at the World's Columbian Exposition of 1893 in Chicago, and the Mission Inn, along with the Electric Tower of the Pan-American Exposition in Buffalo in 1900 introduced the potential of Spanish Colonial Revival. They also integrated porticoes, pediments and colonnades influenced by Beaux Arts classicism as well.

By the early years of the 1910s, Florida was major center for Spanish Colonial Revival style in the United States. Frederick H. Trimble's Farmer's Bank in Vero Beach, completed in 1914, is a fully mature early example of the style. The city of St. Cloud, Florida, espoused the style both for homes and commercial structures and has a fine collection of subtle stucco buildings reminiscent of colonial Mexico. Many of these were designed by architectural partners Ida Annah Ryan and Isabel Roberts.

One of the most significant examples of the emerging popularity of Spanish Colonial Revival in the United States at the time was the architecture of Coral Gables, Florida. A planned city established in the 1920s, the city's architecture is almost entirely Mediterranean Revival style, mandated in the original plan. The city was developed by George E. Merrick, a real estate developer from Pennsylvania, during the Florida land boom of the 1920s. The Coral Gables Congregational Church, donated by Merrick, and the Catholic Church of the Little Flower, were classic examples of the Spanish Renaissance style. Early in the city's planning and development, Merrick shared his vision for Coral Gables as "a most extraordinary opportunity for the building of 'Castles in Spain'. Merrick's success in executing this vision for the city would catch the attention of Spain's King, Alfonso XIII, who awarded Merrick the Order of Isabella the Catholic for his support of Spanish culture in Coral Gables.
