Niilo is Finnish in Origin.

Niilo is a Finnish masculine name (pronounced NEE-lo) that traces back to Greek Nikolaos, meaning “victory of the people” (nikē “victory” + laos “people”). It entered Finnish usage through Swedish and ecclesiastical channels, paralleling Nils/Niels and the widespread veneration of Saint Nicholas, the 4th‑century bishop of Myra. In Finland, Niilo shares the traditional name day with Nicholas on 6 December.

Documented in Finnish parish records from the early modern period, Niilo has cycled in popularity, with a notable revival in the late 20th and early 21st centuries as parents embraced traditional yet approachable forms. Close variants and cognates include Nils (Swedish/Norwegian), Niels (Danish), Niklas (Scandinavian/German), Nicholas/Nicolas (English/French), and Finnish forms Niko and Niklas; in Sámi, Niila is used.
