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.

MID stayed there for several months before it was relocated to Pearl's Hill (former Lower Barracks of Police).

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