The invention provides a network selection method and apparatus. The method comprises the following steps: when rollback of a mobile communication network to which a terminal accesses at present is determined, storing a first identifier of a current position of the terminal in a rollback list, and starting to perform rollback timing; determining that the terminal initiates network reselection, and when the rollback timing is stilled not terminated, judging whether a second identifier of the position of the terminal has been stored in the rollback list when the terminal initiates the network reselection; and when the second identifier of the position of the terminal is determined to be not stored in the rollback list, stopping the rollback timing, and starting the network reselection. Accordingly, the terminal does not need to perform the network reselection after the rollback timing is terminated, thereby reducing the network reselection delay, and thus the network reselection efficiency is improved.
