The invention relates to an all-fiber laser frequency stabilization device based on a hot atom steam chamber, and the device comprises a first frequency locking assembly of a fiber laser light source and a second frequency locking assembly of a single-frequency fiber laser light source, in the first frequency locking assembly, a feedback signal obtained by a proportional-integral differentiating circuit (14) is transmitted to the first frequency locking assembly, and the feedback signal is transmitted to the second frequency locking assembly. The frequency is fed back to piezoelectric ceramics of the optical fiber laser light source (1) to control the cavity length so as to realize the stable frequency; in the second frequency locking assembly, a feedback signal obtained by the proportional-integral differentiating circuit (30) is fed back to piezoelectric ceramics of the single-frequency fiber laser light source (22) to control the cavity length so as to realize the stability of the frequency.
