The Kharraqan towers (as known as the Kharrakhan or Kharaghan towers; Persian: برج‌های خرقان) are a pair of mausolea built in 1067 and 1093, in the Kharraqan region of northern Iran, near Qazvin. They are notable for being an early example of geometric ornament, an early example of double domes, and one of the earlier tomb towers that appeared in the Seljuk period of medieval Iran during the 11th century.

The octagonal brick structures stand 13 metres (43 ft) tall, and each side is 4 metres (13 ft) wide. The surface of both mausolea demonstrate extensive use of geometry. The interior walls of the older mausoleum are decorated with paintings of various subjects. The eastern tower dates from 1067–68, and the western tower dates from 1093.
