PAP–UMNO relations refers to the occasionally turbulent relationship between the People's Action Party (PAP), the governing party of Singapore since 1959, and the United Malays National Organisation (UMNO), the leading party of the Barisan Nasional coalition which governed Malaysia from 1955 to 2018 and has governed it since 2020. The two parties' relationship has impacted Malaysia–Singapore relations given the countries' geographical proximity and close historical ties.
