Heijō-kyō (平城京, also Heizei-kyō, sometimes Nara no miyako) was the Capital of Japan during most of the Nara period, from 710 to 740 and again from 745 to 784. The imperial palace is a listed UNESCO World Heritage together with other places in the city of Nara (cf. Historic Monuments of Ancient Nara).

Empress Genmei ordered the Imperial capital moved from Fujiwara-kyō to Heijō-kyō in 708, and the move to Heijō-kyō was complete in 710. Heijō-kyō was modeled after Chang'an, the capital of Tang-dynasty China, although Heijō-kyō lacked walls. In the city, merchants and traders from China, Korea and India introduced various foreign cultures to Heijō-kyō through the Silk Road. As a result, Heijō-kyō flourished as Japan's first international and political capital, with a peak population of between 50,000 and 100,000. The overall form of the city was an irregular rectangle, and the area of the city was more than 25 km.

In the area of Heijō-kyō, there are ancient Buddhist temples, and some temples are also listed as UNESCO World Heritage together with Heijō Palace.
