The architecture of Indonesia reflects the diversity of cultural, historical and geographic influences that have shaped Indonesia as a whole. Invaders, colonizers, missionaries, merchants and traders brought cultural changes that had a profound effect on building styles and techniques.

Numbers of Indonesian vernacular houses have been developed throughout the archipelago. The traditional houses and settlements of the several hundreds ethnic groups of Indonesia are extremely varied and all have their own specific history. The houses hold social significance in society and demonstrate local ingenuity in their relations to environment and spatial organisation.[1]: 5 

Traditionally, the most significant foreign influence has been Indian. However, Chinese, Arab, and European influences have also played significant roles in shaping Indonesian architecture. Religious architecture varies from indigenous forms to mosques, temples, and churches. The sultans and other rulers built palaces. There is a substantial legacy of colonial architecture in Indonesian cities. Independent Indonesia has seen the development of new paradigms for postmodern and contemporary architecture.
