**Abstract:**

*We show how string theory can be used to reproduce the
one-loop two-point photon amplitude in noncommutative U(1)
gauge theory. Using a simple realization of the gauge theory
in bosonic string theory, we extract from a string cylinder
computation in the decoupling limit the exact one loop field
theory result. The result is obtained entirely from the
region of moduli space where massless open strings dominate.
Our computation indicates that the unusual IR/UV
singularities of noncommutative field theory do not come
from closed string modes in any simple way.*
