Infrared observations of two T Tauri stars, T Tau and SU Aur, were obtained using long-baseline interferometry with the Palomar Testbed Interferometer (PTI). For both sources, the 2.2 micron emission is resolved at PTF's nominal fringe spacing of 4 milliarcsec. Using simple circumstellar material distributions, we find that the infrared emission region is tenths of AU in size. We also compare our results from PTI with accretion disk models inferred from spectral energy distributions.
