The T2K experiment is a long baseline neutrino oscillation experiment designed to directly measure $\nu_{e}$ appearance, thereby providing a measurement of $\theta_{13}$, the last unknown neutrino mixing angle. In addition, T2K will make precision measurements of $\Delta m_{23}^2 $ and $\sin ^2\left( {2\theta _{23} } \right)$ via measurement of $\nu_{\mu}$ disappearance. To achieve these goals, a beam of muon neutrinos is produced at the Japanese Proton Accelerator Research Complex in Tokai, Japan. At a distance of 280 meters from the the beam origin, a set of detectors has been constructed in order to measure the properties of the beam before oscillation. The Super-Kamiokande detector 295 kilometers away serves as the far detector that measures the beam after oscillation. T2K began the first data taking run in January 2010 and concluded in June 2010 and accumulated 0.323$\times $10$^{20}$ POT. The second data taking run began in November 2010 and concluded in March 2011 and accumulated 1.108$\times $10$^{20}$ POT. I will summarize the results of the analysis from these runs.
