An Easter bonnet is any new or fancy hat worn by women as a Christian headcovering on Easter. It represents the tail end of a tradition of wearing new clothes at Easter, in harmony with the renewal of the year and the promise of spiritual renewal and redemption. As with the wearing of headcoverings by women during Christian prayer and worship in general, the use of Easter bonnets is inspired by the passage of 1 Corinthians 11:1–13 in the Bible.

Easter, also called Pascha or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus Christ, preceded by Lent, a 40-day period of fasting, prayer, and penance.
