Nara (奈良市, Nara-shi; Japanese pronunciation: [naꜜ.ɾa, na.ɾaꜜ.ɕi] ^ⓘ) is the capital city of Nara Prefecture, Japan. As of 2022^[update], Nara has an estimated population of 367,353 according to World Population Review, making it the largest city in Nara Prefecture and sixth-largest in the Kansai region of Honshu. Nara is a core city located in the northern part of Nara Prefecture bordering the Kyoto Prefecture.

Nara was the capital of Japan during the Nara period from 710 to 784 as the seat of the Emperor before the capital was moved to Nagaoka-kyō, except for the years 740 to 745, when the capital was placed in Kuni-kyō, Naniwa-kyō and Shigaraki Palace. Nara is home to eight major historic temples, shrines, and heritage sites, specifically Tōdai-ji, Saidai-ji, Kōfuku-ji, Kasuga Shrine, Gangō-ji, Yakushi-ji, Tōshōdai-ji, and the Heijō Palace, together with Kasugayama Primeval Forest, collectively form the Historic Monuments of Ancient Nara, a UNESCO World Heritage Site.

By the Heian period, a variety of different characters had been used to represent the name Nara: 乃楽, 乃羅, 平, 平城, 名良, 奈良, 奈羅, 常, 那良, 那楽, 那羅, 楢, 諾良, 諾楽, 寧, 寧楽 and 儺羅.

A number of theories for the origin of the name "Nara" have been proposed, and some of the better-known ones are listed here. The second theory in the list, from the notable folklorist Kunio Yanagita (1875–1962), is most widely accepted at present.

The "flat land" theory is adopted by Nihon Kokugo Daijiten (the largest dictionary of Japanese language), various dictionaries for place names, history books on Nara, and the like today, and it is regarded as the most likely.

There are a number of megalithic tombs or kofun in Nara, including Gosashi Kofun, Hishiage Kofun (ヒシアゲ古墳), Horaisan Kofun (宝来山古墳), Konabe Kofun (コナベ古墳), Saki Ishizukayama Kofun (佐紀石塚山古墳), Saki Misasagiyama Kofun (佐紀陵山古墳), and Uwanabe Kofun (ウワナベ古墳).

By decree of an edict on March 11, 708 AD, Empress Genmei ordered the court to relocate to the new capital, Nara. Once known as Heijō or Heijō-kyō, the city was established as Japan's first permanent capital in 710 CE; it was the seat of government until 784 CE, albeit with a five-year interruption, lasting from 741 to 745 CE. Heijō, as the ‘penultimate court’, however, was abandoned by the order of Emperor Kammu in 784 CE in favor of the temporary site of Nagaoka, and then Heian-kyō (Kyoto) which retained the status of capital for 1,100 years, until the Meiji Emperor made the final move to Edo in 1869 CE. This first relocation was due to the court's transformation from an imperial nobility to a force of metropolitan elites and new technique of dynastic shedding which had refashioned the relationship between court, nobility, and country. Moreover, the ancient capital lent its name to Nara period.

As a reactionary expression to the political centralization of China, the city of Nara (Heijō) was modeled after the Tang capital at Chang’an. Nara was laid out on a grid—which was based upon the Handen system—whereby the city was divided by four great roads. Likewise, according to Chinese cosmology, the ruler's place was fixed like the pole star. By dominating the capital, the ruler brought heaven to earth. Thus, the south-facing palace centered at the north, bisected the ancient city, instituting ‘Right Capital’ and ‘Left Capital’ zones. As Nara came to be a center of Buddhism in Japan and a prominent pilgrimage site, the city plan incorporated various pre-Heijō and Heijō period temples, of which the Yakushiji and the Todaiji still stand.
