速不台（蒙古语：ᠰᠦᠪᠦᠭᠠᠲᠠᠢ，鲍培转写：Sübügätäi，西里尔字母：Сүбээдэй；1176年－1248年，又作雪不台、唆伯台、速别额台、书部台等）为蒙古帝国大将，蒙古侵略欧洲中的实际领军主帅，被成吉思汗封为「四狗」之一。曾参与第一和第二次蒙古西征，令帝国版图扩展至俄罗斯一带。其征战所及东至朝鲜半岛的高丽王朝，西达欧洲的波兰、匈牙利等，北到西伯利亚，南抵中国开封，是古代世界征战范围最广的将领。公元1241年窝阔台之死，导致速不台放弃进攻神圣罗马帝国的计划，从而结束了蒙古侵略欧洲战争。

Subutai (Classical Mongolian: Sübügätäi or Sübü'ätäi; Modern Mongolian: Сүбэдэй, Sübedei; Chinese:速不台 1175–1248) was a Mongol general, and the primary military strategist of Genghis Khan and Ögedei Khan. He directed more than twenty campaigns in which he conquered thirty-two nations and won sixty-five pitched battles, during which he conquered or overran more territory than any other commander in history. He gained victory by means of imaginative and sophisticated strategies and routinely coordinated movements of armies that were hundreds of kilometers away from each other. He is also remembered for devising the campaign that destroyed the armies of Hungary and Poland within two days of each other, by forces over five hundred kilometers apart.
