A mamak stall, is a food establishment which serves mamak food. In Malaysia, the term mamak refers to Tamil Muslims, who generally own and operate them. Although traditionally operated from roadside stalls, some modern mamak stall operators have expanded their businesses into restaurant or cafe-type establishments. Mamak stalls tend to be popular among Malaysian youths as hang out spots, due to cheap food and beverages being served 24 hours a day, 365 days a year.

People of all races, religions and ages frequent mamak stalls to gossip or catch a late-night football game while enjoying a cup of hot teh tarik. No other eatery has quite as much cultural significance in Malaysia, save for the kopi tiam.

The Malaysian Mamak (commonly known as Mamak) are Tamil Muslims of Malaysian nationality, whose forefathers mostly migrated from South India to the Malay Peninsula and various locations in Southeast Asia centuries ago. They are regarded as part of the Malaysian Indian community. Indian Muslims were believed to first arrive at Samudera (now Aceh in Sumatra, Indonesia) back in the early 10th century, and later settled down in Peninsular Malaysia. Although the origins of the word are perfectly benign, it is often used as a derogatory term for the Indian Muslim community in Malaysia.
