Description	We apply the BV formalism to non-commutative field theories, introduce BRST symmetry, and gauge-fix the models. Interestingly, we find that treating the full gauge symmetry in non-commutative models typically leads to reducible gauge algebras. As one example we apply the formalism to the Connes-Lott two-point model.
