A hybrid vehicle and a method of controlling engine off are provided. The method includes turning off an engine in a desired state in a hybrid vehicle including a specific type powertrain. Particularly, the method includes entering an engine stop mode, stopping fuel injection and maintaining engine revolution per minute (rpm) in a first range using a first motor. Additionally, the method includes setting a second range of a crank angle of a stop angle control while the engine rpm is maintained in the first range and applying torque for engine off to the first motor when the crank angle is positioned in the set second range. The torque for engine off includes first torque for reducing the engine rpm and second torque for cancelling engine friction torque.
