  In this paper, we investigate the dynamics of pre-inflation with Hilltop
potential in the framework of loop quantum cosmology. The initial conditions of
inflaton field at the quantum bounce is categorized into two classes, first one
is dominated by kinetic energy and second one by potential energy. In both
cases, the physically viable initial values of inflaton field at the bounce are
obtained numerically that generate the desired slow-roll inflation and also
sufficient number of $e$-folds. To be consistent with observations at least 60
$e$-folds are required. In case of kinetic energy dominated initial conditions
of inflaton field at the bounce, the numerical evolution of the background
prior to preheating is divided into three different regions: {\it bouncing,
transition and slow-roll inflation} whereas bouncing and transition phases
disappear in the potential energy dominated case but still slow-roll inflation
is achieved. This is true in case of $p=4$ and $v=1 M_{Pl}$ of Hilltop
potential. However for other cases, slow-roll inflation can not be obtained.
Moreover, we study the phase space analysis for Hilltop potential and discuss
the phase space trajectories under the chosen parameters.
