利奧十世是羅馬教皇、美第奇家族的領袖，在位期間正值文藝復興的鼎盛時期和宗教改革初期，他極力贊助文藝復興，但對宗教改革卻反應遲緩，延誤了和解的時機，未能阻止天主教與新教分裂，爲後世所詬病。本文試圖就利奧十世在宗教改革初期所扮演的角色及其歷史貢獻進行論述。

Leo X was the Pope of Rome and the leader of the Medici family. During his reign, the Renaissance was at its peak and the Reformation was in its early stages. He strongly sponsored the Renaissance, but was slow to respond to the Reformation, which delayed the opportunity for reconciliation and failed to prevent the split between Catholicism and Protestantism, and was criticized by later generations. This article attempts to discuss the role played by Leo X in the early period of the Reformation and his historical contribution.
