In this paper, the perturbation method is employed to obtain an approximate solution of some examples of the Bratu equation by choosing the different values of $ \varepsilon $  and comparison with the exact solutions. It can be seen that the perturbation method is an alternative technique to be considered in solving many practical problems involving differential equations.
