Hassanal Bolkiah Mosque, Islamic prayer center in Mukim Mentiri, Brunei.

Hassanal Bolkiah Mosque is a prayer facility in Mukim Mentiri featuring white walls decorated with geometric Islamic patterns. The building accommodates approximately 600 worshippers and includes separate prayer areas for men and women.

The mosque was built after fire destroyed the previous religious building in April 2017. Construction of the new structure took place between May and June of that year.

The mosque is named after Sultan Hassanal Bolkiah, who ordered its construction and opened it on 23 June 2017 after the first Friday prayers held there. It replaced the Kampong Mentiri National Housing Scheme Mosque, destroyed by fire on 5 April 2017, and serves the Muslim community of Mentiri for daily and Friday worship.

The mosque stands in Mentiri, in Brunei-Muara District, and is reached by road from Bandar Seri Begawan. It was opened on 23 June 2017, after the first Friday prayers held there. Visitors should dress modestly and follow entry rules for non-worshippers, which are set locally rather than posted online.

The mosque replaced the Kampong Mentiri National Housing Scheme Mosque, which burned down on 5 April 2017. Construction began on 2 May 2017, the foundation stone was laid three days later, and the Sultan opened the building on 23 June 2017 after the first Friday prayers held there.
