Fractional branes on the non-compact orbifold <sup>3</sup>/<sub>5</sub> are studied. First, the boundary state description of the fractional branes are obtained. The open-string Witten index calculated using these states reproduces the adjacency matrix of the quiver of <sub>5</sub>. Then, using the toric crepant resolution of the orbifold <sup>3</sup>/<sub>5</sub> and invoking the local mirror principle, B-type branes wrapped on the holomorphic cycles of the resolution are studied. The boundary states corresponding to the five fractional branes are identified as bound states of BPS D-branes wrapping the 0-, 2- and 4-cycles in the exceptional divisor of the resolution of <sup>3</sup>/<sub>5</sub>.
