The invention discloses an adjustable guide vane of a megawatt-level low-temperature air centrifugal compressor, and belongs to the technical field of compressors. The adjustable guide vane solves the problems that according to an existing adjustable guide vane, a shell and an adjustable diffuser are prone to being jammed, flow field distribution is uneven when media pass through, and the problems that a ring bearing is adopted, the structure is complex, and cost is high are solved. A pneumatic executing mechanism is connected with a driving rod and drives the driving rod to rotate; the driving rod drives the main connecting plate and the driving blade to coaxially rotate; the main connecting plate drives the rotating ring to move through the main joint bearing while rotating; the rotating ring and the adjustable guide vane holding ring form a cylindrical surface pair, so that the rotating ring rotates and translates along the axial direction; the rotating ring drives the ten driven blades to rotate through t
