An automatic focusing device for a camera comprises a distance measuring mechanism for calculating the distance to an object by performing distance measurement a plurality of times and a focusing lens driving mechanism for moving a focusing lens to a position where it is focused on the object on the basis of the object distance calculated by the distance measuring mechanism. A field depth detecting device for detecting the depth of field of a photographing lens is provided. A device setting the number of times that distance measurement is performed by the distance measuring mechanism in accordance with the depth of field detected by the field depth detecting device is provided in such a manner that, if the depth of field detected is relatively great, the number of times that distance measurement is performed is set to a relatively small number, whereas, if the depth of field detected is relatively shallow, the number of times that distance measurement is performed is set to a relatively large number.
