General elections were held in Singapore on 30 May 1959. They were held under the new constitution and were the first in which all 51 seats in the Legislative Assembly were filled by election. This was the first election victory for the People's Action Party (PAP), as they won a landslide victory with 43 seats. The party has remained in power ever since.

The Workers' Party is a major centre-left political party in Singapore and one of the three contemporary political parties represented in Parliament, alongside the governing People's Action Party (PAP) and the opposition Progress Singapore Party (PSP). It is currently the largest and oldest opposition party in Parliament, having contested every parliamentary election since 1959 against the dominant PAP. The WP is the only political party other than the PAP with elected Members of Parliament (MPs) since the 1991 general election.
