《威尼斯之死》（德语：Der Tod in Venedig，又译《魂断威尼斯》）是德国小说家托马斯·曼的中篇小说，发表于1912年，是托马斯·曼最优秀的作品之一。

故事描写一位德国慕尼黑的作家古斯塔夫·冯·奥森巴哈（Gustav von Aschenbach）因长年刻苦严谨的写作生涯而感到倦怠。一天，他突然看见一个肩上扣着一只帆布包的怪家伙似乎是去旅行，他这时“企图尽力摆脱本身的工作和刻板的、冷冰冰的、使人头脑发胀的日常事务”，于是前往水都威尼斯度假，住在丽都岛的“至上饭店”（Hotel Exelsior）。

Death in Venice is a novella written by the German author Thomas Mann, first published in 1912 as Der Tod in Venedig. The work presents a great writer suffering writer's block who visits Venice and is liberated, uplifted, and then increasingly obsessed, by the sight of a stunningly beautiful youth. Though he never speaks to the boy, much less touches him, the writer finds himself drawn deep into ruinous inward passion; meanwhile, Venice, and finally, the writer himself, succumb to a cholera plague. The novella is powerfully intertextual, with the chief sources being first the connection of erotic love to philosophical wisdom traced in Plato's Symposium and Phaedrus, and second the Nietzschean contrast between the god of restraint and shaping form, Apollo, and the god of excess and passion, Dionysus.
