Kovil or koyil (meaning: residence of god)^{[N 1]} is the Tamil term for a distinct style of Hindu temple with Dravidian architecture.

Both the terms koyil (கோயில், kōyil) and kovil (கோவில், kōvil)^[1] are used interchangeably. In Tamil, kōvil (wikt:ta:கோவில்)^[2] is the word derived, according to the rules of Tamil grammar.^{[N 2]}

In contemporary Tamil, the term 'kōvil' is also used to refer to "Place of Worship". In modern formal speech, kōvil is also referred to as aalayam, dheva sthaanam by many Hindus. Ambalam is another term used by devotees of the 19th century Tamil monk Vallalar. Another term is 'Thali' (தளி),^[3][4] which also means temple.

For Vaishnavites the foremost kōvils are, Sri Ranganathaswamy temple, Srirangam and Tirumala Venkateswara temple, Tirupati are viewed as important While for Shaivites, the foremost kōvils are Chidambaram temple and Koneswaram temple are important.

There are over 36,488 Temples in Tamil Nadu alone as registered by Hindu Religious and Charitable Endowments Department. The Sangam literature scripted before the common era, refers to some of the temples the early kings of Tamilagam had erected. The songs of the revered Vaishnava Alvar saints that date back to the period 5th to the 10th century CE and the Shaiva Nayanars that date back to the period 7th to the 10th century CE provide ample references to the temples of that period. Stone inscriptions found in most temples describe the patronage extended to them by the various rulers.

The most ancient temples were built of wood as well as brick and mortar.^[6] Up to about 700 CE temples were mostly of the rock-cut type. The Pallava kings were great builders of temples in stone. The Chola dynasty (850–1279 CE) left a number of monuments to their credit such as the Brihadeeswarar Temple in Thanjavur. The Cholas added many ornate mandpams or halls to temples and constructed large towers. The Pandya style (until 1350 CE) saw the emergence of huge towers, high wall enclosures and enormous towered gateways (Gopurams). The Vijayanagara Style (1350–1560 CE) is famous for the intricacy and beauty especially for the decorated monolithic pillars. The Nayak style (1600–1750 CE) is noted for the addition of large prakaram (outer courtyard) (circum-ambulatory paths) and pillared halls.
