BESIII is an experiment located at the Institute of High Energy Physics in Beijing, China. It consists of a state-of-the-art 4π magnetic spectrometer that surrounds the beam-beam intersection region of the BEPCII e+e- collider that is operated by an international collaboration of nearl 400 researchers from 13 countries. BEPCII provides BESIII with record-high luminosity e+e- data over a center-of-mass energy range that includes the thresholds for pair production of all of the stable strange baryons, charmed mesons, -leptons and c charmed baryons, and direct access to charmonium and many of the XYZ charmoniumlike mesons that are strong candidates for non-standard, four-quark mesons. This talk will focus on a subset of recent BESIII results, including some unexpected phenomena seen at different baryon-antibaryon thresholds and high statistics measurements of properties of the Y(4260) that provide some insight into its underlying structure.
