A steering behavior monitoring apparatus based on a long short term memory (LSTM) and a method thereof are disclosed. According to the present invention, the steering behavior monitoring apparatus based on LSTM comprises: an information acquisition unit which acquires a data set related to a vehicle driving environment; a learning unit for learning a steering behavior prediction model by inputting the data set into the LSTM-based steering behavior prediction model and mapping the steering angle corresponding to the data set; a prediction unit which inputs the data set at a time point T into the learned steering behavior prediction model and predicts the steering angle at a time point (T+1) by referring to a long-term state vector and a short-term state vector before the time point T; and a monitoring unit for monitoring a steering behavior by comparing the predicted steering angle with the actual steering angle obtained by vehicle manipulation.
