Thiere or tyere or cere from Wolof cere, itself from the Serer name Ceereer ne (the Serer people); or saadj in Serer or Saay in Serer Saafi and Cangin, is a millet based Senegalese couscous. It is traditionally consumed during evenings or special occasions such as weddings or Tamkharit, the Muslim new year Ashura in Wolof.

Thiere is very versatile and can be eaten with fermented milk or cream and sugar as a breakfast cereal or prepared just as a standard couscous.
