The Long March 6A (Chinese: 长征六号甲运载火箭) or Chang Zheng 6A as in pinyin, abbreviated LM 6A for export or CZ 6A within China, is a Chinese medium-lift launch vehicle in the Long March family, which was developed by the China Aerospace Science and Technology Corporation (CASC).^[6]

The vehicle is a further development of the Long March 6, with two YF-100 engines on the first stage as opposed to one on the Long March 6, augmented by four solid rocket boosters. The Long March 6A is China's first rocket with solid rocket boosters, and only one so far to combine solid and liquid fuel technology in one rocket.^[7] There also exists a shorter boosterless variant of the 6A called the Long March 6C.

The maiden launch of the Long March 6A took place on March 29, 2022, successfully reaching orbit.^[8] It was also the first launch from the newly built launch complex 9A in Taiyuan.
