The Ministry of Home Affairs (MHA; Malay: Kementerian Ehwal Dalam Negeri; Chinese: 内政部; Tamil: உள்துறை அமைச்சு), sometimes referred to as the Home Team, is a ministry of the Government of Singapore responsible for overseeing the national security, public security, civil defence, border control and immigration of Singapore.

The Ministry of Home Affairs was created in 1959 when Singapore attained self-governance from the United Kingdom.

The ministry was housed at the Empress Place Building until 16 September 1963, when Singapore joined Malaysia and internal affairs became a federal responsibility.

MHA remained at Pearl's Hill until August 1977 when it moved to Phoenix Park at Tanglin Road.

The incumbent minister is MP for Nee Soon GRC K. Shanmugam from the People's Action Party.
