Easter Saturday, or Bright Saturday, is the Saturday following the Christian festival of Easter. In the liturgy of Western Christianity it is the last day of Easter Week, sometimes referred to as the Saturday of Easter Week or Saturday in Easter Week. In the liturgy of Eastern Christianity it is the last day of Bright Week. Easter Saturday is the day preceding the Octave Day of Easter (also known as St. Thomas Sunday or Divine Mercy Sunday).

Easter Saturday sometimes refers to Holy Saturday, the Holy Week observance that falls between Good Friday and Easter Sunday, but this usage is incorrect.

In the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite, this day is known as "Bright Saturday", and is the last day of Bright Week. All of the services for Pascha (Easter) are repeated every day of Bright Week (georgi week Catholics and Easter), except for the hymns from the Octoechos. On Bright Friday, the Resurrection hymns from the Octoechos are taken from Tone Eight. Before the dismissal of Matins a crucession (procession headed by the cross) takes place, going three times around the outside of the temple (church building), while chanting the Paschal Canon (in parish churches, this crucession often takes place after the Divine Liturgy).
