  We study a geometric transition in non-perturbative topological string. We
consider two cases. One is the geometric transition from the closed topological
string on the local $\mathcal{B}_{3}$ to the closed topological string on the
resolved conifold. The other is the geometric transition from the closed
topological string on the local $\mathcal{B}_{3}$ to the open topological
string on the resolved conifold with a toric A-brane. We find that, in both
cases, the geometric transition can be applied for the non-perturbative
topological string. We also find the corrections of the value of K\"ahler
parameters at which the geometric transition occurs.
