A Low Density Parity Check (LDPC) encoding apparatus and method are provided. The LDPC encoding apparatus includes a controller for determining a number of zeros b to be inserted in an input information vector when a length of the input information vector is less than a length of a use information vector of a parity-check matrix, for selecting b stopping sets Sd using the parity-check matrix, for selecting one variable node from each of the b stopping sets Sd using a selection scheme, and for determining positions corresponding to the selected variable node from each of the b stopping sets Sd as positions where zeros are to be inserted.
