The 2018 China League One (Chinese: 58同城 2018中国足球协会甲级联赛) was the 15th season of the China League One, the second tier of the Chinese football league pyramid, since its establishment in 2004. The league's title sponsor is the e-commerce website 58.com. Dalian Transcendence, Heilongjiang Lava Spring, Meizhou Hakka, Meizhou Meixian Techand and Nei Mongol Zhongyou failed to submit the application for the Chinese Super League before deadline, thus ineligible for promotion.
