盎博罗削图书馆（意大利语：Biblioteca Ambrosiana）是意大利米兰一座历史悠久的图书馆，盎博罗削画廊（Pinacoteca Ambrosiana）亦设于此。它得名于米兰的主保圣人盎博罗削，由枢机主教费德里科·博罗梅奥（1564年至1631年）创建，其代理人遍及西欧，甚至远达希腊和叙利亚，寻找书籍和手稿。整个图书馆被完整收购的情况包括本笃会博比奥修道院（1606）以及帕多瓦的文森佐·庇尼的收藏，他的800余手稿在送往米兰时装满了70个盒子，其中包括著名的《伊利亚特》（《盎博罗削伊利亚特》）。

The Biblioteca Ambrosiana is a historic library in Milan, Italy, also housing the Pinacoteca Ambrosiana, the Ambrosian art gallery. Named after Ambrose, the patron saint of Milan, it was founded by Cardinal Federico Borromeo (1564–1631), whose agents scoured Western Europe and even Greece and Syria for books and manuscripts. Some major acquisitions of complete libraries were the manuscripts of the Benedictine monastery of Bobbio (1606) and the library of the Paduan Vincenzo Pinelli, whose more than 800 manuscripts filled 70 cases when they were sent to Milan and included the famous Iliad, the Ilia Picta.
