The Tuanku Mizan Zainal Abidin Mosque, or Iron Mosque (Malay: Masjid Tuanku Mizan Zainal Abidin or Masjid Besi) is the second principal mosque in Putrajaya, Malaysia after Putra Mosque. It is located in Putrajaya?s Precinct 3, opposite the Palace of Justice. Construction began since April 2004 and was fully completed on August 2009. It was officially opened by the 13th Yang di-Pertuan Agong, Tuanku Mizan Zainal Abidin on 11 June 2010.

The mosque was built to cater to approximately 24,000 residents including the government servants working around the city center as well as areas within Precincts 2, 3, 4 and 18. Tuanku Mizan Zainal Abidin Mosque?s area is twice that of Putra Mosque, which is located 2.2 kilometres north.

The ?Iron Mosque? features a district cooling system, and fans or an air conditioning system. The mosque employs ?architectural wire mesh? imported from Germany and China, which is also constructed at the Santiago Bernab?u Stadium in Madrid and the Biblioth?que nationale de France in Paris. The main entrance is strengthened with glass reinforced concrete to increase the integrity of the structure and uses fine glass to create an illusion of a white mosque from afar.

There is a mihrab wall made of 13-meter-high glass panel imported from Germany inscribed with two verses from Sura Al-Baqarah on the right and Sura Ibrahim on the left. The mihrab wall is designed so that no light will be reflected, creating an illusion that the verses are floating on air. The 40-feet-long edges of the mosque?s roof are able to shelter the people praying outside of the main prayer hall from rain.
