There has been a renewed interest in 2D metal chalcogenide heterostructures (2DMCHs) in the context of their exceptional optoelectronic properties and potential for a wide variety of practical applications. However, the controllable synthesis of 2DMCHs remains a huge challenge. Recently, chemical vapor deposition (CVD) has been proposed to be an efficient way to realize high‐quality, large‐scale, and layer‐controllable 2D materials and has also shown high feasibility in 2DMCHs. Here, the latest controllable CVD growth strategies of 2DMCHs are introduced. The designed growth techniques mainly focus on three vital factors in CVD: source supply, mass transport, and substrate engineering. Then, the emerging novel applications of 2DMCHs are also systematically reviewed with particular attention to memory, infrared photodetector, and moiré superlattice, which have demonstrated significant progress in recent years. Finally, future opportunities and remaining challenges concerning the developments of 2DMCHs are presented.
