László József Bíró (Hungarian: [ˈlaːsloː ˈjoːʒɛf ˈbiːroː];  Schweiger; 29 September 1899 – 24 October 1985), Hispanicized as Ladislao José Biro, was a Hungarian inventor who patented the first commercially successful modern ballpoint pen. The first ballpoint pen had been invented roughly 50 years earlier by John J. Loud, but it was not a commercial success.
