The Zhengzhou–Shenzhen high-speed train (郑深高速动车组列车) are high-speed train services between Zhengzhou, the capital city of Henan Province, and Shenzhen, a major city in Guangdong Province.

The services are operated on the Beijing–Guangzhou–Shenzhen–Hong Kong HSR and Zhengzhou–Jiaozuo ICR (G75 only).

The G73 train departs from Anyang East instead of Zhengzhou East, but it still takes Zhengzhou East as an intermediate stop, while G75 takes its intermediate stop at Zhengzhou railway station and doesn't go past Zhengzhou East.

The G75/G74 service is operated by 16-car CRH380AL trainsets of CR Zhengzhou while the G76/G73 service uses the same type of trainsets of CR Guangzhou.
