Jilin is a province of the People's Republic of China located in the northeastern part of the country. Jilin borders North Korea and Russia to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. The name was transliterated to Kirin before standardization to pinyin.

The name "Jilin" probably originates from Girin ula, a Manchu term meaning "along the river"; this was transcribed into Jilin wula in Chinese, then shortened to Jilin. The literal meaning of the Chinese characters for "Jilin" is "auspicious forest".

Jilin has a northerly continental monsoon climate, with long, cold winters and short, warm summers. Average January temperatures range from -20 to -14¡ãC. Rainfall averages at 350 to 1000 mm.

The Goguryeo sites and tombs found in Ji'an, Jilin, including Wandu, Gungnae Fortress, and the pyramidal General's Tomb, have been listed as part of a UNESCO World Heritage Site.

The Baekdu Mountain, especially Heaven Lake on the border with North Korea, are popular tourist destinations due to their natural scenery.

Ancient Tombs at Longtou Mountain, including the Mausoleum of Princess Zhenxiao, are royal tombs of the Balhae kingdom found in Yanbian Korean Autonomous Prefecture.
