Narquelië was the Quenya word for the tenth month of the year according to the Steward's Reckoning, or the calendar of the Men of Gondor in Middle-earth. It would have corresponded to our October, though it actually ran from 22 September until 21 October.

Narquelië was also known as Narbeleth in Sindarin and as Winterfilth in the reckoning of the Shire.
