Disclosed in the disclosure is a battery pack, a vehicle, and a monitoring method for thermal runaway thereof. The battery pack includes: a cell set, including a plurality of single cells stacked in sequence; an end plate, provided along a stacking direction of the plurality of single cells on an end of the cell set; a monitoring structure, provided on at least one lateral surface that is parallel to the plurality of single cells and the end plate, configured to monitor an expansion deformation value of the plurality of single cells; a battery management system, BMS, electrically connected to the monitoring structure, configured to calculate a deformation rate and a deformation velocity in a preset time according to the expansion deformation value so as to determine whether the battery pack is in a thermal runaway state according to the deformation rate and the deformation velocity.
