The present invention relates to a plasma display apparatus and driving method thereof, wherein application time points of data pulses applied to address electrode groups, where each group includes one or two address electrodes, are controlled. This results in a reduction of noise generation. The benefits of reducing noise include enhancing the driving efficiency of the plasma display panel and preventing electrical damage to driving circuits. The plasma display apparatus includes a plasma display panel including a plurality of address electrodes, a data driving unit that drives the plurality of the address electrodes, and a data pulse controller that controls the data driving unit to make application time points of the data pulses, which are applied to neighboring address electrode groups, to be different from each other.
