Yichun (Chinese: 伊春; pinyin: Yīchūn) is a prefecture-level city on the Songhua river in Heilongjiang province, People's Republic of China.

Before the Tang dynasty, the region was inhabited by several nomad tribes in the northeastern border area of China including Sushen and Donghu.

During the Qing dynasty, Yichun was under the administration of Qiqihar and Hulan's Deputy Lieutenant-General (Fudutong) before it became a minor town under Tangyuan County's jurisdiction in the 1890s.

In November 1941, a railway from Suihua to Jiamusi was built before its branch was extended to today's Yichun district from Nancha in July 1942.

Yichun has a monsoon-influenced, hemiboreal climate (Köppen Dwb), with long, bitterly cold, but very dry winters, and very warm, humid summers.

During the warmer months, rainfall is somewhat enhanced by the mountainous topography, allowing for a generous annual precipitation total of 627 millimetres (24.7 in).
