An apparatus and a method for detecting an attention level of a driver are provided. The apparatus includes an electrocardiogram (ECG) sensor that measures ECG of a driver and a controller that calculates a standard deviation of NN interval (SDNN) quantifying an attention level of the driver using the ECG measured by the ECG sensor and detects the attention level of the driver based on the calculated SDNN.
