尼科利（Niccolò de' Niccoli，1364年－1437年）意大利文艺复兴时期人文主义者。

尼科利的出生和逝世都在佛罗伦萨。他是科西莫·德·美第奇门下一个重要文人。科西莫·德·美第奇之于他，正如同奥古斯都之于梅塞纳斯。尼科利在古典文学领域的主要工作是古代写本的抄写、整理和校勘，并为之划分章节，开列目录。

他的出色品味弥补了其在考据方面的缺憾。尽管他对希腊文知之甚少，但他在这方面有嘉玛道理会士盎博罗削（Ambrogio Traversari）的协助。现在罗伦佐图书馆（Biblioteca Laurenziana）的珍贵抄本大多处于他的手笔，其中包括卢克莱修和普劳图斯的十二部喜剧。

Niccolò de' Niccoli (1364 – 22 January 1437) was an Italian Renaissance humanist.

He was born and died in Florence, and was one of the chief figures in the company of learned men which gathered around the patronage of Cosimo de' Medici. Niccoli's chief services to classical literature consisted in his work as a copyist and collator of ancient manuscripts; he corrected the text, introduced divisions into chapters, and made tables of contents.
