Disclosed are a beam measurement method, a terminal and a network device. The method comprises: a terminal receiving measurement configuration information sent by a network device, wherein the measurement configuration information is used for indicating a parameter used when measuring at least one beam; the terminal measuring the at least one beam according to the measurement configuration information to obtain a measurement result; and the terminal sending the measurement result to the network device. By means of the beam measurement method in the present application, a terminal receives measurement configuration information sent by a network device and measures a beam according to the measurement configuration information to obtain a more accurate measurement result based on the beam, so that it is beneficial for the network device to configure the terminal more efficiently according to the measurement result.
