The Sri Mariamman Temple (Tamil: ஸ்ரீ மாரியம்மன் கோவில், romanized: Srī Māriyam'maṉ Kōvil) is Singapore's oldest Hindu temple. It is an agamic temple, built in the Dravidian style. Located at 244 South Bridge Road, in the downtown Chinatown district, the temple serves the majority Hindu Singaporeans, Tamilians, in the city-state. Due to its architectural and historical significance, the temple has been gazetted a National Monument and is a major tourist attraction. Sri Mariamman Temple is managed by the Hindu Endowments Board, a statutory board under the Ministry of Community Development, Youth and Sports.

The Sri Mariamman Temple was founded in 1827 by Naraina Pillai, eight years after the East India Company established a trading settlement in Singapore. Pillai was a government clerk from Penang who arrived in Singapore with Sir Stamford Raffles on his second visit to the island in May 1819. Pillai went on to set up the island's first construction company, and also entered the textile trade. He rapidly established himself in business and was identified as a leader of the Indian community.
