With recent and archival Rossi X-ray Timing Explorer (RXTE) X-ray measurements of the heavily obscured X-ray pulsar IGR J16393-4643, we carried out a pulse timing analysis to determine the orbital parameters. Assuming circular orbits, we phase-connected data spanning over 1.5 years. The most likely orbital solution has a projected semi-major axis of 43 +/- 2 lt-s and an orbital period of 3.688 +/- 0.001 days.
