Nénimë is a Quenya word for the second month of the year in the calendars of the Men of Middle-earth. It would correspond to modern day February, though it actually ran from 22 January until 20 February.

The same month of the year had other names as well. It was known as Nínui in Sindarin and was called Solmath in the calendar of the Shire.
