The BESIII Experiment at the Beijing Electron Positron Collider (BEPC2) has accumulated the world's largest samples of e+e- collisions in the tau-charm region. From these samples - which include J/psi, psi(2S), and psi(3770) decays, among others - BESIII has produced many new results in the spectroscopy, transitions, and decays of charmonium. This talk will review the current status of these analyses, which cover a wide range of topics from rare decays to radiative transitions to new precision measurements.
