The mass spectrum of the noncommutative QED in two-dimensional Euclidean R2 space is derived first in a perturbative approach at one-loop level and then in a nonperturbative approach using the equivalent bosonized noncommutative effective action. It turns out that the mass spectrum of noncommutative QED in two dimensions reduces to a single noninteracting meson with mass M = g / sqrt(p), as in commutative Schwinger model.
