Quasi-neutral　limit　of　the　multidimensional　isentropic　two-fluid　Euler-Poisson　system　is　rigorously　justified.　For　well-prepared　initial　data,　as　the　Debye　length　goes　to　zero,　the　convergence　of　the　bipolar　Euler-Poisson　system　to　the　compressible　Euler　equations　is　proved　in　the　time　interval　where　a　smooth　solution　of　the　limit　problem　exists.
