Lêerdeling is die praktyk van die verspreiding of verskaffing van toegang tot digitale media, soos rekenaarprogramme, multimedia (oudio, beelde en video), dokumente of elektroniese boeke. Lêerdeling kan op verskeie maniere bereik word. Algemene stoor-, transmissie- en verspreidingsmetodes sluit in deling deur gebruik maak van verwisselbare media, sentrale bedieners op rekenaarnetwerke, skakels op webwerwe, en die gebruik van verspreide eweknienetwerke.
