Bursa is a city in northwestern Turkey and the administrative center of Bursa Province. The fourth-most populous city in Turkey and second-most populous in the Marmara Region, Bursa is one of the industrial centers of the country. Most of Turkey's automotive production takes place in Bursa.

Bursa was the first major and second overall capital of the Ottoman State between 1335 and 1363. The city was referred to as Hüdavendigar ("God's gift", a name of Persian origin) during the Ottoman period, while a more recent nickname is Yesil Bursa ("Green Bursa") in reference to the parks and gardens located across its urban fabric, as well as to the vast and richly varied forests of the surrounding region. Mount Uludag, the ancient Mysian Olympus, towers over it, and has a well-known ski resort. Bursa has rather orderly urban growth and borders a fertile plain. The mausoleums of the early Ottoman sultans are located in Bursa, and the city's main landmarks include numerous edifices built throughout the Ottoman period. Bursa also has thermal baths, old Ottoman mansions, palaces, and several museums.

The shadow play characters Karagöz and Hacivat are based on historic personalities who lived and died in Bursa in the 14th century.

Bursa stands on the northwestern slopes of Mount Uludag (known as the Mysian Olympus in classical antiquity), on the banks of the Nilüfer River, in the southern Marmara Region. It is the capital city of Bursa Province, which borders the Sea of Marmara and Yalova to the north; Kocaeli and Sakarya to the northeast; Bilecik to the east; and Kütahya and Balikesir to the south.
