Masjid Wilayah Persekutuan, Ottoman-style mosque in Segambut district, Kuala Lumpur, Malaysia

The Federal Territory Mosque (Masjid Wilayah Persekutuan) stands off Jalan Tuanku Abdul Halim near the MATRADE complex, its pale stone walls topped by a central pale-blue dome with a pointed finial and flanked by two cream minarets, the right taller than the left. Smaller blue domes and half-domes cluster around the main one above a wide arched facade with a circular traceried window. Its 22 domes are made of glass fibre fabric mixed with epoxy resin.

Construction took place between 1998 and 2000 on a 5-hectare site off Jalan Duta, near the MATRADE complex and the Federal Government Complex. The mosque opened to the public on 25 October 2000 and was officiated on 18 February 2005 by Tuanku Syed Sirajuddin ibni Almarhum Syed Putra Jamalulail, the 12th Yang di-Pertuan Agong. It was the 44th mosque built by the government within Kuala Lumpur and holds 17,000 worshippers.

The mosque is run by the Federal Territory Islamic Religious Department (JAWI), and its grounds also hold Sekolah Kebangsaan Agama Ibnu Khaldun, a national religious primary school. Its design follows the Blue Mosque in Istanbul, so the Ottoman forms visitors see are a deliberate reference rather than local tradition.

The building is located near the MATRADE complex and is easy to reach. Visitors should note that access may be limited during midday prayer times on Fridays.

The mosque holds a Sekolah Kebangsaan Agama Ibnu Khaldun, a national religious primary school, on its grounds, so pupils attend classes beside the prayer hall. Its 22 domes are made of glass fibre fabric mixed with epoxy resin, chosen to keep them light and durable.
