Raihani binti Sulaiman Shah (11 October 1911 â 22 September 1993) was Queen of Brunei as the wife of Sultan Ahmad Tajuddin. She was also a member of the Selangor royal family as the daughter of Sultan Sulaiman Shah.
Tengku Raihani was born on 11 October 1911, at Istana Bandar Temasya in Jugra, Kuala Langat, Selangor to Sultan Sulaiman of Selangor and one of his consorts, Cik Anjung Negara Cik Puan Maimunah binti Abdullah.
In April and May of 1934, Raihani married Sultan Ahmad Tajuddin of Brunei in two weeks of elaborate ceremonies in Klang, Selangor. The Akad Nikah took place on 30 April at Sultan Sulaiman Mosque and the Bersanding ceremony took place on 6 May at Istana Mahkota Puri.

On 18 August 1956, Raihani married Raja Kamaluddin ibni Raja Harun Al-Rashid, a member of the Perak royal family, at Istana Bukit Kota in Klang.
Tengku Raihani served as the Queen consort of Brunei from the date of her marriage in 1934 until her husband died in 1950. She was given the title of Tengku Ampuan Brunei similar to how the royal consort of the Sultan of Selangor is titled as opposed to using Raja Isteri like other Bruneian royal consorts.
