The Tuanku Munawir Royal Mosque (Malay: Masjid Diraja Tuanku Munawir) is a mosque in Seri Menanti, the royal capital of the Malaysian state of Negeri Sembilan. It is situated next to the Seri Menanti Royal Mausoleum.

The original mosque in Kampung Tanjung Beringin, situated 500 metres north of the current mosque, was built in 1885 on a parcel of land donated by Tuanku Muhammad, the seventh Yang di-Pertuan Besar. Currently, the mosque is out of usage and is gazetted as a national heritage building.

Groundbreaking of the current mosque started in 1964, which was officiated by Tuanku Munawir, the Yang di-Pertuan Besar at the time, and it finished construction and inaugurated in 1970. The site where the mosque is standing is also a mortmain of the Negeri Sembilan royal family.^[1]

The mosque exhibits strong Mughal influence with a hint of Modernist twist in its architecture. Its design consists of a large main golden dome in the centre surrounded by four minarets erected at each corner of the mosque building, and a smaller dome crowning the mosque's portico. The mosque can accommodate up to 1,500 worshippers at once.^[2]
