Classical Ottoman architecture is a period in Ottoman architecture generally including the 16th and 17th centuries. The period is most strongly associated with the works of Mimar Sinan, who was Chief Court Architect under three sultans between 1538 and 1588. The start of the period also coincided with the long reign of Suleiman the Magnificent, which is recognized as the apogee of Ottoman political and cultural development, with extensive patronage in art and architecture by the sultan, his family, and his high-ranking officials.

Ottoman architecture is an architectural style or tradition that developed under the Ottoman Empire over a long period, undergoing some significant changes during its history. It first emerged in northwestern Anatolia in the late 13th century and developed from earlier Seljuk Turkish architecture, with influences from Byzantine and Iranian architecture along with other architectural traditions in the Middle East. Early Ottoman architecture experimented with multiple building types over the course of the 13th to 15th centuries, progressively evolving into the classical Ottoman style of the 16th and 17th centuries. This style was a mixture of native Turkish tradition and influences from the Hagia Sophia, resulting in monumental mosque buildings focused around a high central dome with a varying number of semi-domes. The most important architect of the classical period is Mimar Sinan, whose major works include the Şehzade Mosque, Süleymaniye Mosque, and Selimiye Mosque. The second half of the 16th century also saw the apogee of certain decorative arts, most notably in the use of Iznik tiles.
