Data-driven evaluations of the hadronic light-by-light contribution to the muon anomalous magnetic moment rely critically on precise experimental inputs. This talk presents recent and ongoing measurements from the BESIII experiment specifically targeted to constrain these theoretical frameworks. Utilizing the large $e^+e^-$ datasets collected at the BEPCII collider, we extract single- and...
