Renaissance Revival architecture is a group of 19th-century architectural revival styles which were neither Greek Revival nor Gothic Revival but which instead drew inspiration from a wide range of classicizing Italian modes. Under the broad designation Renaissance architecture 19th-century architects and critics went beyond the architectural style which began in Florence and Central Italy in the early 15th century as an expression of Renaissance humanism; they also included styles that can be identified as Mannerist or Baroque. Self-applied style designations were rife in the mid- and later 19th century: "Neo-Renaissance" might be applied by contemporaries to structures that others called "Italianate", or when many French Baroque features are present.

Architectural revivalism is the use of elements that echo the style of a previous architectural era that have or had fallen into disuse or abeyance between their heyday and period of revival. Revivalism, in a narrower sense, refers to the period of- and movement within- Western architectural history during which a succession of antecedent and remenescent styles were taken to by architects, roughly from the late 18th century, and which was itself succeeded by Modernism. Notable revival styles include Neoclassical architecture, and Gothic Revival. Revivalism is related to historicism.
