Hoysala architecture is the building style in Hindu temple architecture developed under the rule of the Hoysala Empire between the 11th and 14th centuries, in the region known today as Karnataka, a state of India. Hoysala influence was at its peak in the 13th century, when it dominated the Southern Deccan Plateau region. Large and small temples built during this era remain as examples of the Hoysala architectural style, including the Chennakesava Temple at Belur, the Hoysaleswara Temple at Halebidu, and the Kesava Temple at Somanathapura. These three temples were accorded UNESCO world heritage site status in 2023. Other examples of Hoysala craftsmanship are the temples at Belavadi, Amruthapura, Hosaholalu, Mosale, Arasikere, Basaralu, Kikkeri and Nuggehalli. Study of the Hoysala architectural style has revealed a negligible Indo-Aryan influence while the impact of Southern Indian style is more distinct.

Hindu temple architecture as the main form of Hindu architecture has many varieties of style, though the basic nature of the Hindu temple remains the same, with the essential feature an inner sanctum, the garbha griha or womb-chamber, where the primary Murti or the image of a deity is housed in a simple bare cell. For rituals and prayers, this chamber frequently has an open space that can be moved in a clockwise direction. There are frequently additional buildings and structures in the vicinity of this chamber, with the largest ones covering several acres. On the exterior, the garbhagriha is crowned by a tower-like shikhara, also called the vimana in the south. The shrine building often includes an circumambulatory passage for parikrama, a mandapa congregation hall, and sometimes an antarala antechamber and porch between garbhagriha and mandapa. In addition to other small temples in the compound, there may be additional mandapas or buildings that are either connected or separate from the larger temples.
