MYDIN was founded in August 1957 by the late Tuan Mydin Mohamed in Kota Bharu, Kelantan. The first shop was a small wooden shop in Jalan Tok Hakim, Kota Bharu, selling toys and general goods.

With the help of his children, he expanded the business to Kuala Terengganu in 1979 and later marked a step further by the opening of its first branch in Kuala Lumpur at Jalan Masjid India in 1989.

With the company's vision to become the world's leading distributor of competitive Halal Goods and Services, the company has then grown tremendously to present day.

In 2013, MYDIN ventured into premium retail with the opening of SAM's Groceria; the words SAM's is an acronym for Saya Anak Malaysia. The first store opened at the Kuala Lumpur Sentral railway station.

To date, MYDIN has 65 branches nationwide, including 28 MYDIN Supermarkets, 17 MYDIN Emporiums, 3 MYDIN Bazaars, 3 MYDIN Mart franchises, 5 convenience stores operating as MyMart, 7 MYDIN supermarket and 2 premium stores known as SAM’S Groceria.

This is a list of Mydin stores around Malaysia as of May 2021. Note that Emporiums and Mydin Marts operates as one wholesale supermarket, and is not located at retail mall buildings.^{[2][better source needed]}
