A mama shop or mamak shop (from Tamil மாமா māmā, meaning uncle or elder) is a convenience store or sundry shop in Singapore that is often located under a high-rise apartment block built by the Housing and Development Board (HDB). Traditionally, they are owned and operated by Indians. Unlike other stores such as 7-Eleven, mama shops are not air-conditioned and sell a variety of provisions within their limited area of approximately 9 square metres (97 sq ft). Local residents often make use of mama shops as location markers.
