列奧納多·達·芬奇（意大利語：Leonardo da Vinci；儒略歷1452年4月15日－1519年5月2日）[註 1]，又譯達文西，全名列奧納多·迪·塞爾·皮耶羅·達·芬奇（Leonardo di ser Piero da Vinci，意為“芬奇城皮耶羅先生之子──列奧納多”），是意大利文藝復興時期的一個博學者：在繪畫、音樂、建築、數學、幾何學、解剖學、生理學、動物學、植物學、天文學、氣象學、地質學、地理學、物理學、光學、力學、發明、土木工程等領域都有顯著的成就。這使他成為文藝復興時期人文主義的代表人物，也是歷史上最著名的藝術傢之一，與米開朗基羅和拉斐爾並稱文藝復興三傑。小行星3000為紀念達·芬奇而被命名為“列奧納多”。

Leonardo da Vinci (English: /ˌliːəˈnɑːrdoʊ də ˈvɪntʃi, ˌliːoʊˈ-, ˌleɪoʊˈ-/;^[a] 14/15 April 1452^[b] – 2 May 1519) was an Italian polymath of the High Renaissance who is widely considered one of the greatest painters of all time (despite fewer than 25 of his paintings having survived).^[c] The Mona Lisa is the most famous of Leonardo's works and the most famous portrait ever made. The Last Supper is the most reproduced religious painting of all time and his Vitruvian Man drawing is also regarded as a cultural icon. He is also known for his notebooks, in which he made drawings and notes on science and invention; these involve a variety of subjects including anatomy, cartography, painting, and palaeontology. Leonardo's collective works compose a contribution to later generations of artists rivalled only by that of his contemporary Michelangelo.
