The density matrix renormalization group method is generalized to one-dimensional random systems. Using this method, the energy gap distribution of the spin-1/2 random antiferromagnetic Heisenberg chain is calculated. The results are consistent with the predictions of the re- normalization group theory demonstrating the effectiveness of the present method in random systems. The possible application of the present method to other random systems is discussed.
