The present invention relates to a method and an apparatus for controlling a terrain driving mode of a hybrid vehicle. The method for controlling the terrain driving mode of the hybrid vehicle according to the present invention may comprise the following steps of: defining a required torque required to drive a vehicle according to a driver's request and an environment of a driving road; differentiating the required torque in response to the terrain driving mode; calculating accumulated driving energy from a time of operation of the terrain driving mode based on the differentiated required torque; and determining a terrain driving method based on an SOE in consideration of the calculated accumulated driving energy and an SOC and a voltage condition of a battery cell. An object of the present invention is to provide the method and the apparatus for controlling the terrain driving mode of the driving hybrid vehicle for improving fuel efficiency of the vehicle.
