Second Empire, in the United States and Canada, is an architectural style most popular between 1865 and 1900. Second Empire architecture developed from the redevelopment of Paris under Napoleon III's Second French Empire and looked to French Renaissance precedents. It was characterized by a mansard roof, elaborate ornament, and strong massing and was notably used for public buildings as well as commercial and residential design.

The Napoleon III style, also known as the Second Empire style, was a highly eclectic style of architecture and decorative arts, which used elements of many different historical styles, and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and the United States. Major examples of the style include the Opéra Garnier (1862–1871) in Paris by Charles Garnier, the Bibliothèque nationale de France, and the Church of Saint Augustine (1860–1871). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the Opéra, were intended as the focal points of the new boulevards.

Second Empire architecture in Europe is an architectural style rooted in the 16th century Renaissance, which grew to its greatest popularity in Europe in the second half of the nineteenth century and early years of the twentieth century. As the style evolved from its origins, it acquired a mix of European styles, most notably the Baroque, often combined with mansard roofs and low, square based domes. It derived its name from the era of the Second French Empire.
