The Long March 6C (CZ-6C) (Chinese: 长征六号丙运载火箭) is a Chinese two-stage-to-orbit liquid-fueled launch vehicle designed and manufactured by Shanghai Academy of Spaceflight Technology, a subsidiary of China Aerospace Science and Technology Corporation. The rocket is a dual engine first stage variant of the Long March 6; alternatively, it may be considered to be a slightly shorter single stick variant of the Long March 6A. Both the first and second stages of the rocket use liquid oxygen and RP-1 propellants. It is employed to launch small and medium-sized military, civilian and commercial satellites to LEOs and Sun-synchronous orbits; it is capable of lifting 2,400 kg to 500 km SSOs.

The rocket undertook a successful maiden launch on 7 May 2024 at 13:21 UTC from North China's Taiyuan Satellite Launch Center.

A rideshare launch opportunity by Long March 6C was sold at an online auction in July 2023, with bidding prices starting at ¥87,000/kg.
