The Parliament House is a public building and a cultural landmark in Singapore. It houses the Parliament of Singapore, and is located in the Civic District of the Downtown Core within the Central Area. Within its vicinity is Raffles Place, which lies across from the Parliament House from the Singapore River, and the Supreme Court's building across the road. The building was designed to represent a contemporary architectural expression of stateliness and authority. The prism-shaped top, designed by President Ong Teng Cheong, was similarly a modernist take on the traditional dome.

The Parliament of Singapore is the unicameral legislature of the Republic of Singapore, which governs the country alongside the president of Singapore. Largely based upon the Westminster system, the Parliament is made up of Members of Parliament (MPs) who are elected, as well as Non-constituency Members of Parliament (NCMPs) and Nominated Members of Parliament (NMPs) who are appointed. Following the 2020 general election, 93 MPs and two NCMPs from three political parties were elected to the 14th Parliament. Throughout the sitting of Parliament, nine NMPs are usually appointed by the president on a biennial basis.
