Provided are an automatic focusing method in which a photograph region is brought into focus through automatic movement of a focal lens to a focal position, in response to a photographing-command signal, and a digital photographing apparatus using the method. The method includes dividing the photograph region into a plurality of sub-regions, focusing on the sub-regions and obtaining focal position values DS<SUB>FOC</SUB>, calculating an average focal position value ADS<SUB>FOC </SUB>of the focal position values DS<SUB>FOC</SUB>, selecting focal position values DS<SUB>FOC </SUB>whose differences from the average focal position value ADS<SUB>FOC </SUB>are equal to or less than a threshold value D<SUB>TH</SUB>, and moving the focal lens to a focal position corresponding to the focal position value DS<SUB>FOC </SUB>having the shortest focal distance among the selected focal position values DS<SUB>FOC</SUB>.
