The Long March 4C, also known as the Chang Zheng 4C, CZ-4C and LM-4C, previously designated Long March 4B-II, is a Chinese orbital carrier rocket. It is launched from the Jiuquan and Taiyuan Satellite Launch Centres, and consists of 3 stages. Long March 4C vehicles have been used to launch the Yaogan-1, Yaogan-3 SAR satellites and the Fengyun-3A polar orbiting meteorological satellite. On December 15, 2009 a Long March 4C was used to launch Yaogan 8.

Because it was still designated as Long March 4B-II at the time of its maiden flight, the first launch is often mistaken for a Long March 4B. The Long March 4C is derived from the Long March 4B, but features a restartable upper stage, and a larger payload fairing.
