Scottish baronial or Scots baronial is an architectural style of 19th-century Gothic Revival which revived the forms and ornaments of historical architecture of Scotland in the Late Middle Ages and the Early Modern Period. Reminiscent of Scottish castles, buildings in the Scots baronial style are characterised by elaborate rooflines embellished with conical roofs, tourelles, and battlements with machicolations, often with an asymmetric plan. Popular during the fashion for Romanticism and the Picturesque, Scots baronial architecture was equivalent to the Jacobethan Revival of 19th-century England, and likewise revived the Late Gothic appearance of the fortified domestic architecture of the elites in the Late Middle Ages and the architecture of the Jacobean era.

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.
