An input device for reducing an erroneous operation and a mobile terminal having the same are disclosed. The input device includes: a first manipulating unit that has a plurality of movement directions based on a reference position and performing an input operation corresponding to each movement direction; a second manipulating unit disposed around the first manipulating unit and inputting information in a touch (tactile) manner; and an erroneous input detecting unit, which is installed to allow detection of user touches between the first and second manipulating units, can distinguish user inputs that were not intended to be made on the second manipulating unit, by comparing the signals generated when the second manipulating unit is actually operated and the signals generated by erroneous touches made adjacent to the second manipulating unit.
