List of political parties in Singapore in the context of "Nominated Member of Parliament"

General elections in Singapore must be held within three months after five years have elapsed from the date of the first sitting of a particular Parliament of Singapore, as per the Constitution. However, Parliament can also be dissolved and a general election called at the behest of the Prime Minister before the five-year period elapses. The number of constituencies or electoral divisions is not permanently fixed by law, but is declared by the Prime Minister prior to each general election pursuant to the Parliamentary Elections Act (Cap. 218, 2011 Rev. Ed.), which governs the conduct of elections to Parliament, taking into account recommendations of the Electoral Boundaries Review Committee.

In Singapore, the Parliament is unicameral. For the 2025 general election, there are 97 elected seats in Parliament organised into 15 Single Member Constituencies (SMCs) and 18 Group Representation Constituencies (GRCs). Each SMC returns one Member of Parliament (MP) while each GRC returns between three and six MPs, at least one of whom must be from the Malay, Indian or other minority communities. A group of persons wishing to stand for election in a GRC must all be members of the same political party, or a group of independent candidates. The voting age in Singapore is 21, although the age of majority is 18.

The Workers' Party (WP) is a major social democratic political party in Singapore and one of the two contemporary political parties represented in the 15th Parliament, alongside the governing People's Action Party (PAP).

The WP sits on the centre-left of the political spectrum and is currently the largest and oldest opposition party in Parliament, having contested every parliamentary election since 1959 against the dominant PAP. Since the 2011 general election, the WP has been the only political party, other than the PAP, with elected Members of Parliament (MPs).

A Non-constituency Member of Parliament (NCMP) is a member of an opposition political party in Singapore who, as stipulated in Article 39 of the Constitution and the Parliamentary Elections Act, is declared to have been elected a Member of Parliament (MP) without constituency representation, despite having lost in a general election, by virtue of having been one of the opposition candidates with the highest vote shares among the unelected.

NCMPs enjoy all of the privileges of ordinary members of Parliament, apart from the salary, which is substantially lower. The NCMP scheme is a unique feature not seen in traditional Westminster system styles of government. The number of NCMPs seats in Singapore has been progressively raised since the scheme's introduction in 1984, starting with a cap of three, increased to six in 1997, nine in 2010 and finally twelve in 2016.
